RE: IHTSDO meeting - term binding presentation available
Hi All, As written below most of IHTSDO:s activities are currently performed inside IHTSDO:s "Collaborative space" (also known as "Basecamp"). This Collaborative space is a legacy system from before IHTSDO acquired SNOMED CT and probably not the best system due to the current needs, but the system is still there because of lack of time to change system. However, there are now ongoing discussions and there seems to be a new project initiated to supplement or replace the current Collaborative space to make it easier for people outside IHTSDO:s groups to get information and share resources. More information about how to get access to the Collaborative space is, as written below, available at http://www.ihtsdo.org/about-ihtsdo/collaborative-space/. The currently existing Special Interest Groups at the Collaborative space are: Anesthesia Special Interest Group Concept Model Special Interest Group Education Special Interest Group Implementation SIG International Pathology & Laboratory Medicine SIG Machine & Human Readable Concept Model Project Mapping SNOMED CT to ICD-10 Project Nursing Special Interest Group Pharmacy Special Interest Group Primary Care Special Interest Group Translation Special Interest Group And the currently existing project groups are: Anatomy Model Project Collaborative Editing Project Group Enhanced Release Format, Interchange Format & RefSet PG Event, Condition and Episode Model Project Workbench RefSet Module Project Observable and Investigation Model Project Organism & Infectious Disease Model Project Pre-coordination Roadmap Project Request Submission Project Substance Hierarchy Redesign Project Translation Standard Processes Project There are also a affiliate forum.

Unfortunately, the IHTSDO (www.ihtsdo.org), who is responsible for the ongoing management and development of SNOMED CT, is still a somewhat closed and traditional standards development organisation. It has no publicly accessible wiki of resources à la openEHR. It does, however, have a substantial community of individuals from member countries and affiliate organisations and several collaborative websites and mailing lists where ideas, contributions, new specifications etc. are documented and evolve. I would guess that the majority of participants are either active in other standards development organisations, or staff/affiliates of member nation health informatics programs such as the UK's NHS Connecting for Health Program, Canada's Infoway, Australia's National E-Health Transition Authority, etc. 2. For many years prior to IHTSDO taking over SNOMED CT from the College of American Pathologists, SNOMED CT embraced a mechanism and format for producing "subsets" of SNOMED CT. About 18 months ago, proposals for a new SNOMED release format and a new Reference Set format (to replace the old subset mechanism) emerged and evolved. These two proposals morphed into a single umbrella specification called Release Format 2, which has now reached Draft for Trial Use status within the IHTSDO. One of the specification documents covers Reference Set formats and is available in part 2 of RF2 at: http://www.ihtsdo.org/publications/draft-for-review-and-trial-use/ . This draft specification includes support for "language refsets", which may be of particular interest to you. Access to the collaborative space where these documents are made available is described at: http://www.ihtsdo.org/about-ihtsdo/collaborative-space/ . 3. To my knowledge there is no formal IHTSDO proposal for a query language to express Refset membership specifications. However, the IHTSDO Terminology Workbench does incorporate quite a sophisticated mechanism for building refsets using an underlying ( and evolving) query-based expression language. Note: these refsets do not necessarily need to be specific to SNOMED. The refset specifications, however, are currently designed to construct static files for distribution alongside the SNOMED core and national extension files, rather than for producing dynamically evaluated termsets for local needs, as might be supported for openEHR templates, say. eric ---- On 2010-05-06, at 5:48 PM, Sebastian Garde wrote: > Hi Thomas, > > do you know if there is a formal way of how RefSets (=the resulting > Snomed CT codes etc.) and the RefSet query (=the query on Snomed CT to get to the RefSet) are expressed and shared? > Similar to what is described here but based on RefSets: http://www.openehr.org/wiki/display/term/Ocean+Terminology+Query+Language+%2 8TQL%29 > > I agree that RefSets are a good way forward, but they need to be available, reusable and sharable, etc. > > Sebastian > > Thomas Beale wrote: >> >> I attended the IHTSDO meeting just finished in Copenhagen. Things >> look pretty good for where SNOMED CT is going generally - the RF2 technical infrastructure seems relatively well designed. There is a lot of activity in content modeling, the IHTSDO workbench and many other areas relevant to openEHR. Converely, I believe openEHR will be very important to make SNOMED CT work in many places, since it will be via archetypes, templates and associated ref sets that information systems will be able to connect to terminology in a disciplined way. I believe that ref sets are the future of SNOMED CT (and any terminology for that matter) in use in real systems. >> >> I was asked to present a view from openEHR about 'terminology >> binding', i.e. connecting terminology and information models.
