The European Library

Free access to 48 European national libraries with materials in 35 languages.

Not to mention 25 million pages of scanned material read by OCR.

Collection access via several interfaces.

Any library with web access should be able to offer its multi-lingual patrons, Europeans ones anyway, with primary materials in languages of their preference.

Topic map mavens will no doubt want to push further than hyperlinks to language specific collections.

Questions:

Assume your library director has grown tired of “topic maps would…” type suggestions and asks you for a proposal to use topic maps to integrate part of the European Library materials into the local collection.

  1. How would you choose the parts of each collection to be part of the topic map? (2-3 pages, no citations)
  2. What other members of the library staff would you involve in planning the proposal/prototype? (2-3 pages, with attention to the skill sets needed)
  3. Outline your prototype topic map and create a small but workable topic map to demonstrate the mapping you propose to use. (3-5 pages, no citations. Topic map without a custom interface. Very necessary step for a successful topic map deployment but beyond the time we have here.)

SRU Search/Retrieval via URL

SRU Search/Retrieval via URL

Standards, resources, including free implementations for the SRU effort.

SRU: the protocol – SearchRetrieve Operation: Binding for SRU 2.0 (draft)

CQL: The Contextual Query Language – CQL: The Contextual Query Language (draft)

The website reports that standardization is to be completed soon. And the available drafts date from 2010.

However, if you follow known servers you will find only thirteen (13) known servers as of 12 December 2010.

Standards can be written prior to wide spread adoption but before spending too much effort on this protocol and query language, I think we need to watch its adoption curve closely.

Copac

Copaq

From the website:

Copac is a freely available library catalogue, giving access to the merged online catalogues of many major UK and Irish academic and National libraries, as well as increasing numbers of specialist libraries.

Copac has c.36 million records, representing the merged holdings of:

  • members of the Research Libraries UK (RLUK). This includes the catalogues of the British Library, the National Library of Scotland, and the National Library of Wales / Llyfrgell Genedlaethol Cymru.
  • increasing numbers of specialist libraries with collections of national research interest, as well as records for specialist collections held in UK academic libraries.

Copac offers four interfaces:

  • Web interface (+ plugins, including one for Facebook)
  • Z39.50
  • OpenURL
  • SRU

Questions:

  1. OK, so a topic map can merge your local library records with those in Copac. Why? What is your use case for that merging? (3-5 pages, no citations)
  2. What other data would you argue should be linked to Copac records using topic maps? (3-5 pages, no citations)
  3. What APIs at http://www.programmableweb.com would you use with Copac? Why? (3-5 pages, no citations)
