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, email record and so on
• link in HDS database GEsource 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?

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

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 AI
  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
