Rule based mapping
There may be several mappings from a terminology to a classification, depending on the use case. This may need further discussion. I recognize that there is no solid spec on rule based mapping, should it exist other requirements might arise (defer to CTS III?) - I mean, currently, only simple, deterministic mappings are supported, as the initial scope was rather to support HL7 vocabulary needs rather than a general purpose terminology server.
Versioning and Provenance
We understand HL7 CTS 1.0 does not support versioning. We have began implementing our own versioning structures and APIs. We look forward to seeing this topic addressed in version 2.0.
We would welcome some discussion on authoring APIs and collaboration APIs. In evolving, large scale terminologies there should be means to support collaborative development and user feedback/change requests. At least at the vocabulary level, initially. Please note that collaboration/feedback would be easy to standardize, while authoring might depend a lot on many other variables (authoring environment, concept model, artifact (concept, vocabulary, mapping)). Yes, a collaboration API might be easier and more effective in the short term (to standardize the interface between users/vendors and terminology developers) rather than standardizing the actual authoring tool (I mean, something like addDescriptionSugestion rather than addDescription).
The SCT Spanish edition is currently maintained in a collaborative environment through the internet. We see a need to give vendors guidance regarding how they connect their implementations and channel user requests. While the specific authoring webservices are rather specific to our implementation of the vocabulary maintenance workspace.
- Everyone appears to agree that some level of authoring support is needed. Guillermo
