Search for a metadata record

OpenCatalog harnesses the full power of the Isogeo search engine. OpenCatalog features a filter widget and an autocomplete search bar. The combination of the two makes it easy to find the metadata records you're looking for.

Filters

Two tools are available for filtering data:

  • A filter module
  • A search bar

Filter module

Data can be filtered according to the following criteria:

  • Any text to be found in the following metadata fields: title, name, summary, name of associated layer, name of attributes in attribute table
  • the owner if catalogs from several workgroups are shared,
  • one or more keywords,
  • data type,
  • data format,
  • the coordinate system,
  • one or more Inspire themes,
  • one or more possible actions (download, view, other),
  • one or more associated licenses,
  • one or more contacts.

Each time a filter is selected, the number of results and the possible values of other filters are quickly updated. If a new filter is entered and only one value from another filter is available, it is automatically selected.

Filter module

Filter operation

Filters are applied according to an "and" intersection operator, i.e. all the requested criteria must be met for the data to be returned.

A search bar with autocompletion can be used: simply type and then select the proposed field from the list by clicking on Enter.

Search bar

Advanced use: Field nomenclature

It is also possible to directly use the nomenclature of Isogeo fields as described in the API to search for data.

Fields Search nomenclature
Owner owner: owner id tracking
Keywords keyword:isogeo followed by the tag corresponding to the keyword
Type type: tracks tags of one of the four types
Format format: followed by the desired format tag
Coordinate system coordinate-system:followed by the tag corresponding to the coordinate system
Inspirational themes keyword:inspire-theme: followed by the tag corresponding to the inspired theme
Action action: follow the tag corresponding to the desired action
License license: followed by license id
Contact contact: or contact:group: depending on contact type, followed by contact id

For example, searching for the string coordinate-system:2154 action:download is equivalent to selecting the Lambert-93 coordinate system and the action Download.

Parameters in URL

This nomenclature is used in the URL when a query is launched.

Other

  • In the same way as the filter module, data is returned if all criteria are met.
  • Please note: Unlike the filter module, the value "Not filled" is proposed for all fields, regardless of the existing data corresponding to this criterion, as long as no other value for this field is selected

Sorting

The available data can be sorted according to two criteria:

  • sorting direction: ascending or descending
  • sort object: sort by relevance (default), sort alphabetically, sort by metadata update date and sort by data update date
