Museum APIs

Page history last edited by Mia 4 months ago Saved with comment

A collection of museum, gallery, library, archive, archaeology and assorted sources for machine-readable data

 

 

Anyone can edit this page. If you know of an open data service that's not listed, just sign up to add it. If you have some free time, the list of APIs needs to be tidied up a bit, and open cultural data releases (such as images online) could be put on a separate page - feel free to dive in and help out!

 

If you use this to find data for a project or to build another list, it'd be lovely if you credited the wiki/Mia Ridge as its maintainer as it's been a lot of work over the years.)

 

Please add APIs and other data sets you're aware of, ideally with a comment on what's useful or not about how they've been implemented or documented.  If you know of or have written libraries for use with these APIs, then please add them to help other people get started.  It's fine to add your own GLAM API or open cultural dataset - in fact, it's encouraged, whether it's tiny or huge, or whether it's a simple text file or a fancy endpoint. The layout is simple - H2 heading for the title, a brief summary of what's available with which licences and formats, and as many links as you like.

 

Information about schemas/data structures used by other projects is also useful, even if they don't provide an API.  If you're looking for images and books rather than machine-readable data, here's a lot of 'open collections'.  If there's a public-facing collections online site related to the museum API, feel free to include it.  It's also helpful if you can give a rough estimate of the number of records and supported access methods.

 

Designing an API? Check out (and add to) Making good APIs. Thinking of having a hack day to road-test your API?  Check out hackdaymanifesto.com for lots of useful tips.  If you're preparing a list of data sets for a hackday, why not add them to this page and share them more widely?

 

Other sites listing data sources include: DH Toychest: Data Collections and Datasets (curated by Alan Liu); Survey of GLAM open access policies; Micah Walter's list of awesome open access projects; various German-language datasets are available from Coding da Vinci, with related images (without metadata) on Flickr; Open Collections.

Biblioteca Virtual Miguel de Cervantes

'The catalogue of the Biblioteca Virtual Miguel de Cervantes contains about 200,000 records which were originally created in compliance with the MARC21 standard. The entries in the catalogue have been recently migrated to a new relational database whose data model adheres to the conceptual models promoted by the International Federation of Library Associations and Institutions (IFLA), in particular, to the FRBR and FRAD specifications.

The database content has been later mapped, by means of an automated procedure, to RDF triples which employ mainly the RDA vocabulary (Resource Description and Access) to describe the entities, as well as their properties and relationships. In contrast to a direct transformation, the intermediate relational model provides tighter control over the process —for example through referential integrity—, and therefore enhanced validation of the output. This RDF-based semantic description of the catalogue is now accessible online.'

As the first project of NYPL Labs, we're happy to announce that Menus is also the first NYPL project to have a public API. In fact, we use this exact same API to build many of the features of this site.

 


Royal Pavilion and Brighton Museums

http://rpmcollections.wordpress.com/2012/07/20/open-data-from-our-collections/

 

Like any museum, one of our core functions is to make our collections accessible. This applies to the digital data about our collections as much as it does to the physical objects themselves. ...there are many people who would like to use our digitised collections in other ways, whether through analysis of the data we hold, or by re-using this information for other purposes. In recognition of this, we have just released several datasets relating to our collections, along with accompanying images, which are available to download via the Open Data section of our Image Store.

 

Although this only represents a fraction of our total records, this data can be considered ‘clean’ — that is, to the best of our knowledge, the data can be considered accurate, can be illustrated, should be relatively easy to understand, and should not infringe the intellectual property rights of any third party.

 

The datasets are taken from eight of our collections:

Archaeology (17 records)

Costume (193 records)

Craft (33 records)

Decorative Art (1914)

Fine Art (422)

Local Photographs (1777)

Natural Science (40)

Toys (41)

Related images are gathered in a zip file. A link to this can be found by each dataset in the Image Store.


K-samsök / SOCH (Swedish Open Cultural Heritage)

From http://www.ksamsok.se/in-english/: "a web service used to search and fetch data from any organization that holds information or pictures related to the Swedish cultural heritage. ... SOCH functions as an exchange/aggregator where data from many local databases are made searchable and visible to the public and to the research community. ... The beta version was released in February 2009 and by then there were already 1.78 million objects available through SOCH. The number is growing as more content providers hook up, and below you can see the actual number of objects available through SOCH today. The set of objects include archaeological, ethnological and religious objects, as well as ancient monuments, historical buildings and places, and natural objects."

Meketre (Egyptology, linked data)

"reliefs and paintings of Middle Kingdom tombs of Ancient Egypt. The project targets two- dimensional art of the Middle Kingdom (11th to 13th Dynasty, ca. 2040 - 1640 B.C.) and one of its main aims is to map and elaborate the development of the scenes and their content in comparison to the Old Kingdom."

http://www.meketre.org/repository/ 

http://meketre.org/index.php?page=about: "Multimedia content within the MEKETREpository is organized by means of one main taxonomy (in English), which embraces the various themes depicted by the reliefs and paintings in a hierarchical fashion and multiple additional concept schemes (ontologies / controlled vocabularies) that further describe the content. The concept schemes that describe other aspects of the multimedia content (not the depicted persons and things but for example colours, location, age, etc.) are constantly developed in the course of the project, using collaborative ontology building methods. The applied concept schemes are technically represented using standardized web based knowledge organization systems (KOS), in particular the Simple Knowledge Organization System (SKOS) and the Web Ontology Language (OWL).
The implementation of the MEKETREpository software solution utilizes industry-standard technology to ensure both reliability and maintainability. Since the project is expected to develop beyond the three-year limit, it is important to build on a well-proven foundation of software components and a clean, well documented implementation. Therefore we decided to organize the MEKETREpository in a 3-tier style which is very common for many enterprise software solutions.
As stated above, the main focus lies in providing an easy-to-use interface to the collected data. For the user browsing the MEKETREpository, an up-to-date webbrowser (e.g. Firefox 3.0, Internet Explorer 7.0 or Safari 4.0 and, of course all versions above) is sufficient. If the user needs to edit and update information in the repository, he needs to enable Javascript in the browser."

Extract: "Collection images must always credit ‘National Maritime Museum, Greenwich, London’ and link to the original collection record on the NMM collections website. Some collection images have a more restricted licence than CC BY-NC-SA, which you must comply with. Please see our full API documentation for advice on how to exclude such images"


British Museum Semantic Web Collection Online

http://collection.britishmuseum.org/

 

"...Linked Data and SPARQL service. It provides access to the same collection data available through the Museum’s web presented Collection Online, but in a computer readable format. The use of the W3C open data standard, RDF, allows the Museum’s collection data to join and relate to a growing body of linked data published by other organisations around the world interested in promoting accessibility and collaboration.

 

The data has also been organised using the CIDOC-CRM (Conceptual Reference Model) crucial for harmonising with other cultural heritage data. The current version is beta and development work continues to improve the service. We hope that the service will be used by the community to develop friendly web applications that are freely available to the community."

Open Context API

Open Context has some museum content, as well as data from a variety of field-based (mainly archaeological) projects. RESTful web services for Open Context are described here:

 

http://opencontext.org/about/services

 

Essentially, query results are available in paged Atom(+GeoRSS) feeds, KML, and JSON formats. Open Context also makes summaries of query results (bascially facets) availble in these formats.

 

Query parameters include

  • GeoSpatial (Lat / Lon bounding box)
  • Context (Named locations, archaeological contexts)
  • Date Ranges (Start and end dates)
  • Project / Collection name
  • Type / category of item (site, small finds, sculpture, coins, etc.)
  • Related People
  • Descriptive properties (including numeric range searches)
  • Linked Data URIs: Currently Open Context supports queries over URIs to geographic places defined by Pleiades and to biological taxa defined by the Encyclopedia of Life. A description of how to query over URIs and a few examples can be found at: http://opencontext.org/about/services#query-rel

Pleiades

http://pleiades.stoa.org/

'A community-built gazetteer and graph of ancient places...

Pleiades is a historical gazetteer and more. It associates names and locations in time and provides structured information about the quality and provenance of these entities. There is also a graph in Pleiades: names and locations are collected within places and these collections are associated with other geographically connected places. Pleiades also serves as a vocabulary for talking about the geography of the ancient world within Linked Data sets and is referenced by research projects such as Google Ancient Places and PELAGIOS.

 

CSV, KML and RDF datasets can be downloaded from http://pleiades.stoa.org/downloads


Pelagios

Pelagios is a Digital Classics network which aims to interconnect scholarly resources from the domain of Ancient World research through the places they refer to. In principle, any dataset that contains references to places in the ancient world can join the Pelagios data network. Some examples for this are:

  • Text collections that include mentions of ancient places
  • Image collections that depict ancient places in photographs, drawings or maps
  • Database records that describe objects that are located at - or which originate from - an ancient place (e.g. archaeological finds)

Open Images - Newsreel collection

 

Open Images (www.openimages.eu) is an open media platform that offers online access to audiovisual archive material from various sources to stimulate -creative- reuse. Footage from audiovisual collections can be downloaded and remixed into new works. Users also have the opportunity to add their own material to the Open Images and thus expand the collection. Open Images provides an API (http://www.openimages.eu/api), making it easy for third parties to develop mashups.

 

The platform currently (April 2011) offers access to over 1.500 items from various sources, including a considerable number of newsreels from the collection of the Netherlands Institute for Sound and Vision. This amount will grow substantially over the coming years as new items will be uploaded continuously, and as new partners join the initiative.


OPenn - Images and Data from the University of Pennsylvania Special Collections

 

This website contains complete sets of high-resolution archival images of manuscripts from the collection of the University of Pennsylvania Libraries and other institutions, along with machine-readable TEI P5 descriptions and technical metadata. All materials on this site are in the public domain or released under Creative Commons licenses as Free Cultural Works.

 

Files are available through a simple HTML interface or, in bulk, through rsync. 

 

Introduction: http://openn.library.upenn.edu/ReadMe.html

Technical details (including how to bulk download objects and collections): http://openn.library.upenn.edu/TechnicalReadMe.html 


Science Museum 'Cosmic Collections' API

A subset of our data, produced as a beta API for our mashup competition.

 


Brooklyn Museum API

"A set of services that you can use to display Brooklyn Museum collection images and data in your own applications."

http://www.brooklynmuseum.org/opencollection/api/

Methods

  • collection.search
  • collection.getItem
  • collection.getImages

http://www.brooklynmuseum.org/opencollection/api/

Parameters

The methods provided by the API take a range of parameters specific to their individual functions, but all methods rely on these three principal parameters:

method (Required)
Specifies what method to perform (e.g., "collection.search", "collection.getItem")
api_key (Required)
Your personal API Key.
format (Optional)
The response format. Valid formats are xml, json, html. Default xml.

 

A write up here: Hack the Brooklyn Museum:

 

"The API is for non-commercial use with a limit of 3000 API calls a day. Naturally the museum must be respectful of artist copyrights, and requires proper attribution for any display of results. The API also permits only session-based caching with no retention of copies, and the images returned are no greater than 500 pixels in width or height, with many that may be smaller.

The API has a simple REST format with three methods - search, getitem (given the id returned from a search), and getimages for a particular item. The search can be filtered by date, keyword, and whether or not there are images present."

 

[And I just saw that they'd linked here at the end - cool!]

 


Museum of London API

http://www.museumoflondon.org.uk/museumoflondon/food/rest.aspx

A REST interface to the following data sources:

  • publications from the Archaeology Service
  • events at the Museum of London, Museum in Docklands, and London Archaeological Archive and Resource Centre
  • a converter from OSGB grid references to latitude/longitude

Base URL is: http://www.museumoflondon.org.uk/MuseumofLondon/food/rest.aspx?source=events

Output formats: plain XML; RSS2; and RSS2 with xCal, DC and geo extensions as used by Upcoming.

Set the output format by adding:  mode={rss2 or xCal or xml}. Leaving it out returns the plain XML. (?KML output also possible? Hooks in code for plain text and JSON renderings of the output (not implemented?) )

 

 


Celtic Coin Index API

http://www.finds.org.uk/CCI/blog/accessing-the-api/

The Celtic Coin Index is the online incarnation of the Celtic Coin collection at the Institute of Archaeology at Oxford University. The collection began in 1960 and contains photographs and information about coins held in Britain's museums. Coins are still being found and added to the collection.

The API is RESTful and returns responses in JSON, XML, geoRSS, KML, RSS, and CSV.

 


Powerhouse Museum Collection Search (RSS/Opensearch available)

http://www.powerhousemuseum.com/collection/database/menu.php

Image search option also available.

Good example of RESTful query construction and Opensearch/result URI generation.

 


DigitalNZ API

http://www.digitalnz.org/developer

DigitalNZ brings together the metadata of nearly 200 organisations from around New Zealand, and international organisations with New Zealand-related content. Content partners come from the cultural and heritage, broadcasting, education, and government sectors; as well as local community sources and individuals. This metadata is made available via the DigitalNZ API.


The current version of the DigitalNZ API is version 3, versions 1 and 2 have been depcrecated. A subset of the metadata has been made available for commercial use.

 

The custom search records method is perhaps a little unusual. DigitalNZ has a visual search builder tool that allows users to construct complex search queries. This method provides access to that refined dataset.

 

 

Response formats: xml, json, rss. Interesting selection of metadata returns. Minimum metadata response elements include:

  • dc:title - the title of the item, or a brief description if no title exists.
  • dnz:category - the high-level DigitalNZ category(s) that the item belongs to.
  • dnz:content_partner - the organisation who provided the item
  • dnz:landing_url - the preferred URL for linking to the item.
  • dnz:thumbnail_url - the URL of a thumbnail of the item (required for Images, optional for other categories).

 

There's a good post on how to get started with the API, including sample PHP code, here: http://digitalnz.org/blog/posts/building-a-website-on-the-digitalnz-api 

 


Victoria and Albert Museum API

http://www.vam.ac.uk/api  or Victoria and Albert Museum API Docs

We're currently working on a RESTful JSON API for our collections database. It is intended to support our own web apps and widgets first and foremost but also be attractive to third-party developers. I have posted the documentation so that you can see how we've structured things.

 


Reciprocal Research Network API

http://www.rrnpilot.org/api

The RRN API is currently providing programmatic access to Northwest Coast items from 8 Institutions (Brooklyn Museum, McCord Museum, MOA at UBC, NMNH, Pitt Rivers Museum, Sto:lo Research and Resource Management Centre, The Burke at UW, The MAA at Cambridge). We provide a very simple API where any item or list of items can be represented as XML or JSON by appending '.xml' or '.json' to the end of the URI. We'd be open to expanding the scope of the API should there be any interest.

 


Transport Archive data structures

"The Metadata elements used in the project are divided into three categories: Content, Intellectual Property and Instantiation."  These pages appear to date from about 2003 - no time at all in museum years, a few centuries in internet years.

Museum Victoria History and Technology Collections API

The API root uri is located at http://museumvictoria.com.au/collections/api/v1/

 

Currently the only type of requests supported are those made via REST, and there are two response formats currently supported, XML and JSON.

 

http://museumvictoria.com.au/collections/help/api

Like the V&A, we're using the API for our own purposes, but would love to see what other folks might make with our "stuff".

Indianapolis Museum of Art OpenSearch

Artworks on http://www.imamuseum.org are first class content, so they come up as search results in the site the same way a page would. We have exposed the entire site, including collections, through OpenSearch using the Drupal module, http://drupal.org/project/opensearch. As of the 6.x-1.3 version, there were a few bugs that had to be fixed by hand. The OpenSearch endpoint is declared in the HTML headers throughout the site. Here is the primary endpoint: http://www.imamuseum.org/opensearch/ima.

 

Description Schema for IMA OpenSearch

http://www.imamuseum.org/opensearch/ima/{searchTerms}?page={startPage?}&filters={apachesolr:filters?} 

 

The apachesolr:filters declaration was a custom addition, and relies on the Drupal module's filtering ability.

 

Example Searches:

 


American Numismatic Society Collection Database (MANTIS) APIs

The American Numismatic Society's collection of nearly 600,000 objects is accessible through a Solr-based API that allows for querying the collection with the Lucene search syntax and responds in Atom XML.  The Atom feed contains references to the URI for the object as an HTML representation and also alternate links to the XML source of the object as well as RDF, KML, and Atom representations.  The RDF is rather rudimentary and will be improved over time.  A similar Solr-to-KML API exists.

 

Atom: http://numismatics.org/search/feed/?q=*:*
Object KML: http://numismatics.org/search/query.kml?q=*:*
Mint KML: http://numismatics.org/search/mints.kml?q=*:*

 

The functionality and Solr fields are discussed further in the Numishare (the open-source framework for managing and publishing coin collections) blog post: http://numishare.blogspot.com/2011/04/world-of-numismatic-data-at-your.html

 

Examples


http://numismatics.org/search/feed/?q=department_facet:"Islamic" AND weight_sint:[4 TO 5] - All Islamic coins that weigh between 4 and 5 grams

http://numismatics.org/search/feed/?q=type_text:temple AND imagesavailable:true AND department_facet:"Greek"
- Greek coins depicting temples that have been photographed

 


Portable Antiquities Scheme

"The Portable Antiquities Scheme is a partnership project which records archaeological objects found by the public in order to advance our understanding of the past."

"PAS is run by the British Museum ... The data gathered by the Scheme is published on an online database (www.finds.org.uk)."

 

Search results from the PAS database can be accessed as xml, json, kml, atom and rss by the addition of '/format/{format}' to the end of any result set URL 

Records from the PAS database can be accessed as xml, json and csv by the addition of '/format/{format}' to the end of a record URL

Thesaurus terms from the PAS database can be accessed as xml and json by the addition if '/format/{format}' to the end of the URL

 

In the case of search results and thesaurus terms the results are accessed in pages of 30 results. The sets can be paged through by appending /page/{number} at the end of the URL (before or after the '/format/{format}')

 

Examples

Search results: http://finds.org.uk/database/search/results/objecttype/ADZE/format/xml

Record: http://finds.org.uk/database/artefacts/record/id/464434/format/xml 

Thesaurus term: http://finds.org.uk/database/terminology/objects/format/xml


Black Country History

http://blackcountryhistory.org/about/

Black Country History is a searchable website which allows users to find information about documents, maps, photographs, art works, objects and more held by archives and museums services within the Black Country.

The eight partners involved in this website are:

  • Dudley Archives and Local History Service
  • Dudley Museums Service
  • Sandwell Community History and Archives Service
  • Sandwell Museums Service
  • Walsall Local History Centre

http://blackcountryhistory.org/data/

The API is based upon OpenSearch, and by default takes a Lucene style query syntax.  The API is available via a rate limiting proxy, and we don’t issue usage keys: by using the API you agree to having your use of it monitored.  API search requests are limited to 100 requests per hour.  The data made available through the API is licenced as Creative Commons Attribution Non-Commercial 2.0 UK: England & Wales, and you are asked to provide a credit and link back to Black Country History in your application or mashup.

 


Western Australian Museum Sandbox

http://www.museum.wa.gov.au/sandbox/

The API uses REST methods, and can be queried via JSON and XML.

 

Western Australian Shipwrecks

http://www.museum.wa.gov.au/maritime-archaeology-db/wrecks-xml - this will dynamically generate an XML file for download - this contains only Shipwrecks information (no artefact data) - roughly 1500 wrecks.

 

Western Australian Maritime Archaeology Artefacts - Complete API

Full API - http://www.museum.wa.gov.au/maritime-archaeology-db/rest/node/

This contains all Maritime Archaeology data, including numismatics, artefacts and wrecks (roughly 47,200 items).

 

If you'd like to be involved in the beta development of the process - be one of the first to get your hands on our API and do something interesting with it we'd love to hear from you.  Send us an email at: onlineservices [at] museum [dot] wa [dot] gov [dot] au


eHive - software as a service collections management system

http://ehive.com/what-is-ehive

eHive is a hosted collections management system used around the world, particularly by small museums and communities. As at May 2013 there were 600 museum accounts with 200,000 records. The site includes public access to the collection records. Developer tools to support this were expanded in early 2013.

 

The eHive Developers website documents the REST/JSON API, Open Archives Initiative Protocol for Metadata Harvesting support, and a suite of WordPress plugins.

 

The API supports searching, requesting tag clouds, reading object records, adding/removing tags and adding comments. Searching is based on SOLR/Lucene so supports the Lucene query syntax.

 

The OAI-PMH support provides Dublin Core object record metadata for a given museum account.

 

The WordPress plugins support search, object detail pages, museum profile pages, tag clouds, tagging & commenting widgets and object image grids. Shortcuts are provided to allow features like image grids to be embedded in any WordPress page or post.    

 


Harn Museum of Art, University of Florida

 

The Harn Museum of Art at the University of Florida has their digital collections powered by the SobekCM software, and their digital collections are here: http://ufdc.ufl.edu/iharn

 

The Open Source SobekCM software is in use by many galleries, libraries, archives, and museums around the world. The SobekCM software supports harvesting by OAI-PMH, searches and browses as XML, and a JSON API, and all documentation as with all records are freely and openly available: 

http://dloc.com/sobekcm/harvesting 

 


Archaeology Data Service (ADS), UK

 

The Archaeology Data Service supports research, learning and teaching with freely available, high quality and dependable digital resources. It does this by preserving digital data in the long term, and by promoting and disseminating a broad range of data in archaeology, using a variety of avenues, including Linked Open Data.

 

Linked Open Data at the ADS was initially made available through the STELLAR project, a joint project between the University of South Wales, the ADS and Historic England.  The STELLAR project developed an enhanced mapping tool for non-specialist users to map and extract archaeological datasets into RDF/XML, conforming to the CRM-EH ontology (an extension of CIDOC CRM for archaeology). For a full description of the ADS datasets used in this evaluation please see the ADS STELLAR Research Page. The results of the STELLAR project are published from the ADS SPARQL endpoint.

 

ADS also consumes LOD from other sources (Library of Congress, Ordnance Survey, GeoNames, DBpedia and the vocabularies developed as part of the SENESCHAL project) to populate the metadata held within our Collection Management System with URIs, and then publishes the resource discovery metadata for all our archives via our SPARQL endpoint. Details of this process can be found here and here.

 

The ADS SPARQL endpoint is available here:

THE ARCHIVES OF THE PLANET BY ALBERT KAHN

 

The purpose of the Archives of the Planet is to account for “the aspects and the practices of human activity which will inevitably disappear over time”. This large iconographic collection consists of 72,000 Autochrome plates (color photographs on glass plates) and hundreds of hours worth of black and white films. This is the result of the work of photographers recruited by Albert Kahn and sent all around the world. Between 1909 and 1931, the photographers have been to more than fifty countries to record the everyday lives of the inhabitants of the planet.

 

The complete archive is available as Open Data with all the OpenDataSoft feature: map, image gallery, filters, API.

Not sure if you want more Library of Congress APIs, but here are a few others that can be added to the doc if they seem appropriate. :)

Prints and Photographs Online Catalog: More than a Million digitized historical prints and photographs http://www.loc.gov/pictures/api
Chronicling America: Historical American Newspapers 1860-1922: http://chroniclingamerica.loc.gov/about/api/
This last one isn't really (to my knowledge) documented yet. But if you append fo=json to a search in LoC's new cross library search you can get some nice looking JSON. For example, this link gives you the JSON for page 2 of results for digitized maps in American Memory. http://www.loc.gov/search/?q=&fa=digitized%3Atrue|original_format%3Acartographic|site%3Aammem&sp=2&st=grid&fo=json

Hi, I do Drupal (7) and helped to build the new iwm.org.uk website last year.

I have been playing with some of the APIs listed here (great list btw!) and thought I'd share.

For Solr APIs see Search API and Search API Solr modules. We used these to pipe in the IWM collections data. You will need to write some code though, especially to handle the little gotcha's e.g. the NMM Solr interface not using the standard 'select' query as expected by the SolrPHPClient library.

I am about half way through building an Adlib module for Drupal, just a sandbox atm although there is a live demo. http://drupal.org/sandbox/zenlan/1512290 When its a bit more robust I will be looking for feedback, testing and feature requests. (Its quite nice if I say so myself, you type in the url and a bare-bones search system is built for you, after that its a matter of tweaking the views. Still a long way to go though.)

I had a play with the BM's Sparql interface, not being a Sparql expert I had a bit of a learning curve and found that queries timed-out quite a lot. I stopped after a couple of days in case they got annoyed. ;)

I am also helping to test and review a Sphinx module, in case any museums out there use Sphinx (alternative to Solr) for indexing.

Given time and if I win the lottery it would be cool to build modules to talk to all of these APIs. Once an object is piped into a Drupal 'entity class' the possibilities for rendering and usage are vast!

Some time soon I will update my demo site to feature the Amsterdam Museum's Adlib API and the National Maritime Musuem's Solr API.
