Keyword List List
Using the keyword endpoint
Here, categories for events are listed. Events in each category can be found at the
event endpoint using the query parameter keyword. The common keywords
used in all events originate from the general Finnish ontology (yso),
hence the format yso:p4354. Default ordering is decreasing order by the number of events found.
The most common event categories are listed in the two keyword sets helsinki:topics and helsinki:audiences, which list the YSO keywords that are present in most events to specify event main topic and audience.
Keyword text
To find keywords that contain a specific string, use the query parameter text.
Example:
keyword/?text=lapsetFree text
While the previous search is looking for the keywords containg exact matches of the search string,
free_text retrieves keywords on the basis of similarity. Results are
sorted by similarity.
Example:
keyword/?free_text=lapppsetKeyword source
Will restrict keywords to a specific data source.
Example:
keyword/?data_source=ysoShow only keywords with the upcoming events
To show only the keywords which are used in the upcoming events supply the
has_upcoming_events query parameter.
For example:
keyword/?has_upcoming_events=TrueShowing all keywords
By default, only those keywords which have listed events are
displayed. You may display keywords with zero n_events with the
query parameter show_all_keywords.
For example:
keyword/?show_all_keywords=TrueShowing deprecated keywords
By default, deprecated keywords are not displayed. You may also display deprecated keywords with the
query parameter show_deprecated.
For example:
keyword/?show_deprecated=TrueOrdering
Default ordering is decreasing order by the number of events found.
You may also order results by name.
For example:
keyword/?sort=nameGET /v1/keyword/?format=api&page=104&show_all_keywords=True
