Presentation Transcript

  1. Stakeholder workshop, 29 Jan 2003 Report on progress

  2. Overview • outreach and stakeholder engagement underway • produced mock-up • basic working demonstrator built • demonstrate today • hands-on session later • first cut at integrating with geoXwalk server • first cut at quality controlled list of resources • metadata collection started • completed thesaurus study • evaluation underway

  3. Cross-searching NGDF Gateway and its directory services Local database with HE records (sample set) GE:source service analysis stage HDS database analysis stage Additional resources included: COPAC  ESRC REGARD database  BGS Image database  ?(illustration purposes only)

  4. Demonstration

  5. Z spider Z Geospatial dataset cache Z NGDF Z Z COPAC Go-Geo! Record catalogue Z Z Regard Z39.50 BGS/JIDI image collection Z search/present XML/text records Databases local to Data Library Remote databases Perl/PHP Go-Geo! server UDDI Service Registry HTTP CGI HTML records Web browser User

  6. Record databases Digimap server geoXwalk server Z39.50 Geospatial Z search/present XML/text records XML RPC/SOAP Placename->bounding box Bounding box->placename list Map vector display, co-ordinates Perl/PHP OGC Web Map Server HTTP CGI Go-Geo! server HTTP CGI HTML records Web browser Web browser User

  7. Areas for improvement in demonstrator • map browse capability • improved data selection - e.g. small scale data set • user-defined box, choice of NG/LL, polygons? • more data for specific geographies e.g. country MBRs, Northern Ireland, settlement MBRs • geospatial interface • feature type ranking, dealing with duplicate names • indexing (spatial and topic) of metadata • one of the reasons for this workshop is to help identify them!

  8. Features still to be implemented • access through topic listing • visualisation of subset of results • geographic coverage • date coverage • inclusion of place name gazetteer • record formats • output XML as well as HTML • output Dublin Core & NGDF Discovery Metadata Guidelines format • inclusion of HDS database and GE:source • make geo-data gateway searchable by NGDF gateway

  9. Additional features • user profiling • store results to build Enquiry-Organiser • set default behaviours e.g. sort preference, spatial query expansion behaviour • searching using postcode • ‘how search was done’ for each record • could lead on to a ‘more like this’ facility • sorting of result set • e.g. geographic and textual relevance • more databases to be added; worldwide datasets with UK records e.g. GCMD • develop service registry e.g. dates as well as geographic

  10. Metadata ‘matters’ • amended and finalised the HE/FE Application Profile of the NGDF Discovery Metadata Guidelines • reviewed the GEMET, NASA, and UNESCO thesauri and selected the UNESCO thesaurus for the controlled keyword vocabulary • made a cross-comparison between the HE/FE Profile and the ISO 19115 Metadata Standard • reviewed and selected potential sources for geo-spatial datasets; hence, contacts for metadata • created a spreadsheet-based metadata (tool) form and added metadata reference material to the project web pages for metadata providers

  11. Metadata ‘matters’ • sent letters to potential metadata providers • approached the Archaeology Data Service (ADS), the History Data Service (HDS), and the Manchester Information & Associated Services (MIMAS) to request permission to convert some of their metadata records to the HE/FE Application format for portal demonstration purposes • converted 70 metadata records. These include 25 from ADS, HDS and MIMAS and 45 from the EDINA Datacentre

  12. Outreach and evaluation • JISCmail list established • leaflet produced • project web pages available • discussions with various stakeholders • discussions with potential metadata creators • evaluation of Go-Geo interface at UKDA • report and outcomes of this meeting will be written up • planned evaluation with students
