Where next…. Stakeholder workshop, 29 Jan 2003

To the end of the project

3 Metadata matters employ a range of procedures to encourage metadata publication –want to determine which strategies are the most effective expand the HE/FE Application Profile Guidelines –need to serve an eclectic audience that spans multiple disciplines integrate HE/FE Application Profile Guidelines document into the geo-data portal to serve as a reference guide to the individual metadata elements monitor possible changes to metadata standards that could take place in the coming months

4 Technical development continue to develop portal client –e.g. result set sorting function, geographic and temporal visualisations, inclusion of gazetteer and thesaurus pick-menu, record and so on link in HDS database & GE:source so cross-searchable from Portal write mechanisms to output metadata as Dublin Core & NGDF Discovery Metadata Guidelines formats provide gateway so NGDF GIGateway can search local Portal database (and geo-data network)

5 Investigations use of OAI to disclose metadata as an output from the portal how access could be provided to 'deep' geo-spatial resources (data mining) how a comprehensive service would include search and browse, visualisation, exploitation and analysis of geo- spatial data will propose that OGC interoperability specifications are used

6 OGC and interoperability Open GIS Consortium (OGC), a private sector initiative, formed in 1994 aim is to develop software specifications to advance geo- processing interoperability across the GIS industry employing practical testbeds and a consensus specification development process to arrive at open specifications for standard interfaces and protocols defined web service implementation specifications for –Map Services– Gazetteer Services* –Feature (data) Services– Geo-parser Services* –Coverage services– Catalog Services could be used by Data Centres and research institutes to serve up their data to the portal (and elsewhere) ££££ - who pays to establish this infrastructure?

8 Revisiting the data access issue proposing a short feasibility study looking at 2 approaches P2P –data holders/custodians would set up a P2P server on institutional machines and store data within it –metadata published announcing existence of servers and data metadata would also be published to the Go-Geo database –users would use P2P client to search for data on the Go-Geo portal, locate a copy and download to their machine self archiving service –data producers/holders use it to publish data for use by others –requires mechanism for them to provide data, metadata and accompanying documentation –metadata would also be published to the local Portal database

9 Evaluation and outreach formal report of this meeting –further development based on information gained at this meeting further evaluation –internal to UKDA & HDS –via online questionnaire & JISCmail list –usability testing by students and trainers enhancement of information on web page outreach –contributions to newsletters/ publications –attendance at conferences & workshops offer trial access from April offer potential metadata producers the opportunity to submit their comments towards the future design and development of a metadata tool

Our exit strategy

11 Transition to service our goal is for the portal to become a service within the JISC Information Environment following a set up phase, would aim to launch the service in January 2004 creation of portal content will be undertaken and managed by HDS EDINA responsible for hosting the service and for technical development the current project will result in a demonstrator service, further development will be required prior to & post launch

12 Further development proposed activities include –linking in of metadatabases provided by other geo-spatial data service providers e.g. MIMAS and ADS, to establish the geo-data network –tools for submitting metadata records and editing –linking in additional resources this could include relevant subscription A&I databases –addition of user profiling –improvements in spatial searching –development of a facility (the Geo-Locator) to allow the geo- data network to be searchable via the Gateway from other Portals this could include institutional portals all subject to continuing funding from the JISC

Any comments?
