Hinweis der Redaktion

  1. Users and systems are able to access social contributions via multiple interface, via www.worldcat.org , via mobile phone interfaces, via also via a suite of APIs and via widgets such as one on Facebook.   In the OCLC Office of Research a study is currently underway with members of the RLG partnership to assess the value of user contributed name authority additions and corrections. OCLC is also studying community policing of user contribution as a method of protecting quality and rewarding generous contributors. There is considerable potential for further user contribution and services based on contribution. For example, armed with the power to make name authority links and corrections, users could make their own curriculum vitae in the form of a list. There is also much to be learned from successful user contribution sites such as Wikipedia and genealogy web sites, particularly in achieving web-scale.   The potential for creating rich, authoritative and useful bibliographic and associated data is in combining contributions from multiple sources including traditional cataloguing, international files like VIAF, data mining, trade and authors’ rights societies along with user contribution.

  6. The WorldCat API is available to all libraries who contribute their holdings in full to WorldCat and have an agreement. It permits local systems to use enriched WorldCat content in their local systems, perhaps meshing it with content from other sites. Examples of such enriched data include: FRBR work clusters – different editions of works are clustered together for more concise and easier to use displays. The holdings are also presented for works as a whole and are sequenced geographically. Technical details: - accepts as input SRU and OpenSearch protocols; delivers as output MARCXML, Dublin Core, RSS and Atom Syndication formats URL 1 – WorldCat blog includes an entry on using the WorldCat API URL 2 – WorldCat Developer’s Network API web page includes links to users’ presentations (CalState at BigWigs) and reusable Python coding from NYPL
