Healthcare Schema Vocabulary Community Group

This community effort aims to provide medical,healthcare and life-science specialized web schemas and vocabulary through improving and extending the existing schemas, concepts, terms and definitions in vocabulary. Ultimate goal is to enable the use of not only by webmasters but also in indexing health records, healthcare documents, and as a pillar open source of medical and healthcare and life science ontology/vocabulary for formalization of healthcare information.

This will make healthcare and medical data on web easy to describe correctly (with their correct meaning and context), easy to expose /index so ready to be accessible and will highly improve to re-usability and exchanging in semantic way, with their correct meaning and context.

The intention is not to replace existing ontologies, nor making upper level ontology nor creating yet another clinical information model/standards. The aim is mainly to provide most useful and frequently used (so, demand driven) classes and properties related to the medical and healthcare domain. Within this scope all concepts are mapped as far as it's feasible to the existing terminology like SNOMED CT, ICD, LOINC, ATC, RxNorm, HL7 FHIR, etc.

Important pointers for developers and materials

Hi every one,

While we are finalizing the revisit of our last submitted draft, some idea pops up to share pointers to materials anyone can read/review/edit/amend or criticise.

Everyone’s suggestions and comments are encouraged and welcome:

First of all this is the existing native draft:

The following revisit tasks are being done:

Second, the maintenance of the draft is done within the github repository:

If you need to make edits/contribution/suggest new properties/classes or edit definitions/domain/ranges; you can do it directly in RDFa file.

Alternatively you can use the .ttl file injected into protegé (not recommended as protegé support not easily .ttl).

Finally, if you need to follow the whole history from the beginning of this effort you can see archives of messages on:

Github Pull request:

Google group (need to join it):!categories/schemed

Thanks for your commitment all!
