Open Knowledge Foundation Blog » Bibliographica. It’s time to talk a bit about Bibliographica, a new project of the Open Knowledge Foundation. Bibliographica is designed to make it easier for scholars and researchers to share and collect information about work in their field. It provides an open source software platform to create and share semantically rich information about publications, authors and their works. As readers of the Open Knowledge Foundation blog will know we have a long-standing interest in open bibliographic data – from our efforts starting in 2005 to build a database of public domain works, our coordination of the response to the Library of Congress’ Future of Bibliographic Control (2007) and the recent creation of a new working group on open bibliographic data in March this year.

Bibliographica itself, is a long-held dream of Jonathan Gray, OKF’s Community Coordinator – a commons of open data surrounding scholarly communications. The primary “technical” features of Bibliographica are: Get involved Resources. Data Packages - CKAN. Datatriage – Public Domain Works. Note that this does go from actions that might be best classified as 'triage' into actual curation and processing of the data but I'm going to stick with this title for now. Datasets for the JISC Open Bibliography project ¶ MARC interchange records from Cambridge University library (CUL) ~180,000 records The BNB - British National Bibliography - in an "RDF/DC" bespoke model from Britih Library (BL) ~3 million records PLoS RDF triplestore backup (Mulgara backup format) ~unknown UK Pubmed Central 'OA subset' - in NLM-DTD Data scraped from IUCr open access articles (from 'DC/PRISM' in HTML and CIF files) Triage Pattern ¶ 1 - Assess and characterise source 2 - Convert into a 'normalised' format, to reduce number of parsing libraries needed. 3 - Translate model into a sparse FRBR-like model, with entities extracted.

Web service: xISBN [OCLC - WorldCat Affiliate tools]: xOCLCNUM API. Web service: xISSN [OCLC - WorldCat Affiliate tools]: Home. The xISSN Web service supplies ISSNs and other information associated with serial publications represented in WorldCat. Submit an ISSN to this service, and it returns a list of related ISSNs and selected metadata. The service is based on WorldCat, the world's largest network of library content and services. The current xISSN database covers 742,395 ISSNs. Ideal for Web-enabled search applications, such as library catalogs and OpenURL Resolvers, and based on associations made in the WorldCat database, xISSN enables an end user to link to information about alternate versions of serial publications.

How xISSN works ISSNs are associated with each other using librarian-catalogued bibliographic records in WorldCat. Using the xISSN Web service To use the service, you submit an ISSN embedded in a URL to the xISSN server, and the server returns a list of associated ISSNs and relevant metadata. You may receive associated ISSNs in either XML, XHTML, Python, JSON, or Ruby formats. Access. Web service: xISBN [OCLC - WorldCat Affiliate tools]: API. xISBN API Overview The xISBN API provides a set of methods corresponding to a single, known ISBN value. All request formats take a list of named parameters. The required parameter method is used to specify the calling method, the required parameter format is used to specify a response format, such as XML, XHTML, JSON, Python or Ruby formats; the optional parameter fl controls what fields to return; the optional parameter library limits search scope to a library or collection.

For example, to request all editions of 0596002815 [Learning Python], request is: The response is an XML formatted message similar to this example. <? And to request a thirteen digits ISBN number of 0596002815, The response is: <rsp xmlns=" stat="ok"><isbn>9780596002817</isbn></rsp> Worldcat Affiliate ID Search in a library Request <?

Since previous posts about linking to WorldCat Identities are getting out of date, here's a summary of the current API.

There are several ways of linking to Identities: Directly to the pages themselvesOpenURLNameFinder searchesSRU searches The first is by far the simplest. If you have an LCCN for a person (or corporation, or horse, etc.) you can link using that: People that do not have an LCCN can also be referenced directly: We only do this for names without LCCN's, so you can't just stick an arbitrary name in and expect to get an Identity page back. We are attempting to make these links as permanent as possible, so when Ralph finally gets an LCCN associated with him, we will make the above link redirect to that new URI.

OpenURL LINKING OpenURL links are what we use in WorldCat.org to link to pages about people: Here’s the short version, with just last name and OCLC#. --Th. Introducing-thingisbn_14. Home.

Querying DBpedia The DBpedia data set enables quite astonishing query answering possibilities against Wikipedia data. 1.1. There is a public SPARQL endpoint over the DBpedia data set at OpenLink Virtuoso as both the back-end database engine and the HTTP/SPARQL server. There is a list of all DBpedia data sets that are currently loaded into the SPARQL endpoint.

You can ask queries against DBpedia using: the Leipzig query builder at the OpenLink Interactive SPARQL Query Builder (iSPARQL) at the SNORQL query explorer at (does not work with Internet Explorer); or any other SPARQL-aware client(s). Fair Use Policy: Please read this post for information about restrictions on the public DBpedia endpoint. 1.2. There is a public Faceted Browser “search and find” user interface at 1.3.

Open Library APIs. Open Library has developed a suite of APIs to help developers get up and running with our data. We encourage interested developers to join the ol-tech mailing list to stay up-to-date with the latest news, or dive in with our own development team at our bug tracker or our GitHub source code repository. APIs Open Library has a RESTful API, best used to link into Open Library data in JSON, YAML and RDF/XML. There's also an earlier JSON API, which is deprecated now.

This is only retained for backward compatibility. You can also return bibliographic data by simply adding an .rdf/.json/.yml extension to the end of any OL bibliographic identifier.
