National Library of the Czech Republic Integration of digital materials into EDL Adolf Knoll National Library of the Czech Republic Helsinki CENL Workshop 26 September 2007

National Library of the Czech Republic European and other libraries ?

National Library of the Czech Republic What we have via TEL In general mostly integrated search service across several digitized collections (and many NL catalogues) Based on communication protocols such as: – Z39.50 – OAI – SRU Can we do more?

National Library of the Czech Republic More?More? Inclusion of non-NL institutions and non- library objects Inclusion of non-NL institutions and non- library objects Uniform DL interface for viewing the data files esp. images Uniform DL interface for viewing the data files esp. images Integrated user personalization tools Integrated user personalization tools Integrated tools for contributors Integrated tools for contributors Linguistic solutions Linguistic solutions Real ontologies Real ontologies

National Library of the Czech Republic Non-library objects Basic DC compatibility possible Basic DC compatibility possible Virtual representation not complicated Virtual representation not complicated Few OAI-enabled systems Similar elements fed by different content description rules

National Library of the Czech Republic A(L)M Archives: not everything is cultural heritage, but public record Archives: not everything is cultural heritage, but public record Museums, galleries, …: Museums, galleries, …: –Less digital data –Unstructured data –More data without (Internet) access applications (no communication protocols) + other players: institutions and individuals Similar to digital access to manuscripts

National Library of the Czech Republic Different priorities Archives: to store and preserve Archives: to store and preserve Libraries: to store and communicate Libraries: to store and communicate Museums and galleries: to exhibit Museums and galleries: to exhibit Others (communities, societies, and individuals): to share what they do Others (communities, societies, and individuals): to share what they do

National Library of the Czech Republic History of coal mining in Hronov Libraries: 0 Libraries: 0 Web pages of local authorities: digital publications (regional periodicals) in full text Web pages of local authorities: digital publications (regional periodicals) in full text …but these (printed) titles are in libraries …but these (printed) titles are in libraries Web publications of interested people, communities, and societies Web publications of interested people, communities, and societies Czech Geological Survey (photographs) Czech Geological Survey (photographs) Google

National Library of the Czech Republic Uniform interface Can solve distributed data storage Can solve distributed data storage Not always possible due to restrictions Not always desirable Should be based preferably on OAI harvest of descriptions with links… BUT more complicated in reality…..

National Library of the Czech Republic Personalization: users Users should be enabled to create their own environments within DL applications. This means: Tools for elementar grouping of presented documents Tools for elementar grouping of presented documents Tools for free reuse of basic digital objects of which the presented digital documents consist Tools for free reuse of basic digital objects of which the presented digital documents consist Easy on-line clearance of any copyright limitations Easy on-line clearance of any copyright limitations

National Library of the Czech Republic Personalization: contributors Contributors should be enabled active dialogue leading to self-service as to: Authoring tools (where lack of own DL) Authoring tools (where lack of own DL) Validation tools Validation tools Upload of documents into common service (mostly metadata) Upload of documents into common service (mostly metadata)

National Library of the Czech Republic LinguisticsLinguistics The common DL should talk any language of any partner in case he wishes it It should assist the user with: Translation during search (internal linguistic multiplication of search terms) Translation during search (internal linguistic multiplication of search terms) Translation of search results (maybe possible through global/general tools?) Translation of search results (maybe possible through global/general tools?)

National Library of the Czech Republic Ontologies and advanced search The common DL should solve: Relevance of terms ocurrence during search Relevance of terms ocurrence during search Semantic bridging to give consistency of returned search results made on different application of description rules on similar objects Semantic bridging to give consistency of returned search results made on different application of description rules on similar objects Ontological treatment of existing terms based on subject nesting, correlations, and variety of representations Ontological treatment of existing terms based on subject nesting, correlations, and variety of representations

National Library of the Czech Republic Our chances If Google or anybody else makes a DL incl. information about our holdings plus our digitized holdings… – What can we offer in plus? – The problem is that we offer a separated/special approach and are always delayed with more sophisticated search of information – We work in a rather limited area

National Library of the Czech Republic Our future We have an opportunity to create an important (mostly parallel) subset of the world information gateway We have an opportunity to create an important (mostly parallel) subset of the world information gateway EDL needs also subsets for special objects (they can do more detailed work) EDL needs also subsets for special objects (they can do more detailed work) One example could be ENRICH Manuscriptorium for manuscripts (new eContentplus project) One example could be ENRICH Manuscriptorium for manuscripts (new eContentplus project) EDL: portal + partly DL where agreed with contributors (if and at which extent) EDL: portal + partly DL where agreed with contributors (if and at which extent) We cannot overperform Google and similar players We cannot overperform Google and similar players
