This section describes the various options to search for ontologies and terms in the graphical user interface.

Finding ontologies

Global filter

To find an ontology based on its IRI, name, author, owner, or version, enter the desired string fragments (separated by spaces) in the search box on the front (Browse ontologies) page.

Ontology global filter

This filtering is immediately applied as you enter the string in the input field. You can optionally press Enter to capture the search string in the ORR URL. For example, after typing sensor network and pressing Enter in the input field, the URL for the MMI ORR becomes https://mmisw.org/ont/#/so/sensor%20network. Opening this link in a new browser window will automatically trigger the corresponding filtering.

Facets

You can also apply ontology filtering by using the facets on the left hand-side panel in the main page. These facets include Owner, Status, Ontology type, and Hosting mode.

Ontology faceted filtering

In the Owner section you can check the special 'Most recent ontology' checkbox to only display the latest ontology submission per owner (organization or user).

Finding terms

To search for terms in the underlying semantic store, click on the "Term Search" link at the top of the main page browse. Enter your search string and press Enter to execute the search. Hovering your mouse on the SPARQL label next to the input field will show the SPARQL query corresponding to the search. In the example below, the search string is sea water salinity with URL for the MMI ORR becoming https://mmisw.org/ont/#/st/sea%20water%20salinity.

Term search

To separate alternative strings for the term search, use the vertical line character |.
