Pages

Home page - News

This page provides general information on the catalog, and displays the latest changes on the catalog.

Catalog - Search

This is where the users will find the search features:

• full-text search
• advanced filters
• toggles on record kind

Then the search results are displayed as a list of cards. Each cards presents various informations to help find the wanted record.

Dataset, Service, Reuse

The Datahub includes record of three different types : datasets, services and reuses. Each type has its own 'page-type' with fixed sections (if the related data is available in the record) :

• Common sections : General information about the record (abstract, keywords, licensing, update date...), Point of contact, External links, Linked records, User feedbacks and Related datasets

• Specificities by page :

  • Dataset : Preview (Map, Table and Chart), Download and API links, Feature catalog
  • Service : Capabilities
  • Reuse : Main link to reuse

For more details on sections and fields, see Datahub - sections and fields

Organisations

The Datahub also supports records classification by organization. A record is associated to an organization by its contacts, and a list of the oraganizations available in the catalog is displayed in its own tab. When viewing the page of one organization in particular, it's then easy to see all the records of this organization.
