1 The Bath Profile: making Z39.50 interoperable UKOLN is funded by the Library and Information Commission, the Joint Information Systems Committee (JISC) of the Higher Education Funding Councils, as well as by project funding from the JISC and the European Union. UKOLN also receives support from the Universities of Bath and Hull where staff are based. Paul Miller UKOLN Carrol Lunau National Library of Canada
2 Whats wrong with Z39.50? Profiles for each discipline Defeats interoperability? Vendor interpretation of the standard Bib–1 bloat Largely invisible to the user Seen as complicated, expensive and old–fashioned Surely no match for XML/RDF/ whatever. See
3 The Bath Profile Vendors and systems implement areas of the Z39.50 standard differently Regional, National, and disciplinary Profiles have appeared over previous years, many of which have basic functions in common Users wish to search across national/regional boundaries, and between vendors. See activities/z3950/int_profile/bath/
4 Learning from the past The Bath Profile is heavily influenced by ATS–1 CENL DanZIG MODELS ONE Z Texas vCUC. See activities/z3950/int_profile/bath/

6 Doing the work ZIP–PIZ–L mailing list, hosted by National Library of Canada Meeting face–to–face JISC supported a face–to–face meeting in Bath (UK) over the summer of 1999 A draft was widely circulated for comment Profile presented at DC7 in Frankfurt Open Concertation day in the UK Discussion and feedback world–wide See activities/z3950/int_profile/bath/

8 What we proposed Minimisation of defaults Where possible, every attribute is defined in the Profile (Use, Relation, Position, Structure, Truncation, Completeness) Three Functional Areas Basic Bibliographic Search & Retrieval Bibliographic Holdings Search & Retrieval Cross–Domain Search & Retrieval Three Levels of Conformance in each Area. See activities/z3950/int_profile/bath/
9 What we proposed Basic Bibliographic Search & Retrieval Level 0 Author, Title, Subject, Any Level 1 Author, Title, Subject, Standard Identifier, Date of Publication, Any (including more exact ATS searches) Scan. See activities/z3950/int_profile/bath/
10 What we proposed Bibliographic Holdings Search & Retrieval Level 0 Holdings info embedded in the record, etc. Level 1 Access to Locations, Summary Information and Holdings Count. See activities/z3950/int_profile/bath/
11 What we proposed See activities/z3950/int_profile/bath/ Cross–Domain Search & Retrieval Level 0 Creator, Title, Subject, Any Level 1 Creator, Title, Subject, Standard Identifier, Date of Publication, Any (including more exact ATS searches).
12 What we proposed SUTRS and one of UNIMARC or MARC21 for Bibliographic Search results All three at Level 1 (for Targets) SUTRS and Dublin Core (in XML) for Cross–Domain results Other record syntaxes also permitted, but conformant tools must support at least these. See activities/z3950/int_profile/bath/
13 Finishing it off… Consolidate comments, and revise where necessary Direct approaches to international vendors User testing in Canada and Texas ZIG meeting this week ISO Internationally Recognised Profile status during 2000 Addition of Functional Areas and Levels of Conformance as required. See texas/texas.html
14 And now for a quick case study… The United Kingdoms DNER
15 The D… N… what? Distributed National Electronic Resource Policy aspiration of the Joint Information Systems Committee Intended to provide greater access to JISCs Current Content Collection –RDN –AHDS –MIMAS/ EDINA/ Data Archive –EDUSERVE –COPAC –eLib projects etc. See
16 Building the DNER Construction of various Portals to facilitate user–centric access JISC Portal ? Data Centre Portals (EDINA, MIMAS…) Subject Portals (the RDN, etc.) Data Type Portals (images, movies, sound…) Institutional Portals (a Hybrid Library?) Personal Portals (Pauls web!) Also providing other access to discrete resources. See
17 Building the DNER But how can we link these services together? See At the moment, Z39.50 is seen as the only feasible mechanism across the range of services JISC wish to offer.
18 Building the DNER Remaining challenges Authentication hell –Move from endless authentication to single authentication Alignment of different data types –Ordnance Survey maps at Edinburgh –Satellite imagery in Manchester –Electronic journal articles in many formats, etc. –Census data at the Data Archive –Survey data in Manchester –Chemical structures in Manchester Collection Level Description.
