Vocabulary V4 use and support

Is anybody in the community still using v4 of OHDSI Standardized Vocabularies?

Landscape assessment showed that all of the participating data sources are on v5 so we are wondering how many folks who didn’t fill the survey still use v4. Reason quite simple: v4 needs to be supported but it is unclear whether there is an appetite for it.

Tagging @DTorok and @amathe05 who previously commented on the topic.

@DTorok no long has a need for vocabulary v4.

Given that nobody has expressed an interest in V4 over the past 6 months, we are moving with retiring its support. We will touch on it on the next Vocab WG meeting on Jan 23rd noon EST.
