SCC Web Services

The SCC Web Services provides an interface to the terms and descriptions that are related to Source Classification Codes (SCC) found in the Terminology Services (TS) registry.

The web services provided allow searching for SCCs by name or facet, as well as querying an SCC by its code. JSON, XML, or CSV output is returned.

Query Services

Possible facet names include: Activity Value Required?, Code, Data Category, ERT Valid, History, Last Updated Date, SCC Level Four, SCC Level One, SCC Level Three, SCC Level Two, Sector, Status, Tier 1 Code, Tier 1 Description, Tier 2 Code, Tier 2 Description, Tier 3 Code, Tier 3 Description
facetValue[]The value to search for the specified facetName. Multiple values may be passed, separated by double pipe characters (||).
facetQualifier[]The qualifier to use when searching the specified facetName. Possible values: contains, begins, exact. If omitted, contains is used by default.
facetMatchType[]The type of match to perform when searching. Possible values: all_words, any_word, whole_phrase. If omitted, all_words is used by default.
lastUpdatedSinceThe date on or after which the SCC has been modified. If omitted, SCCs will not be filtered by date.
