LexEVS 6.5.1 (Not Released) Release Highlights Include:

Note: This release includes all LexEVS 6.5.0 changes.


Features of this Release

New features in this release focus on updates of the value set loading system.  Since the source of value sets it the NCI Thesaurus (NCIt), and since the NCIt contains logical, computable assertions about what value sets are in it’s system, business logic has moved towards direct access to the code system rather than external defining files.  This has been a collaborative effort with NCIt curators and has resulted in improved loading efficiency of value set definitions and resolved value set coding schemes. 
An additional API that detects value set updates has also been made available.  This represents an additional efficiency for value set loading.  
Other assertions made in the NCIt about the hierarchical style storage of value sets also now have an API as well.  This is specific to the NCIt source at this time.  
This release will also contain a prototype of a direct to source value set resolution and search service, based on the kind of assertions the NCIt makes about it’s value sets.  Terminologies that make similar assertions my also make use of this API.  It should make some earlier value set API’s obsolete while retaining the ability of users to define and load their own value sets.
Some value set querying mechanisms are better optimized based on additional methods that provide more tailored object contents for methods requiring a list of value sets without resolving other attributes that may slow performance.

Issues Fixed in this Release

Many issues were reported with the large amount of new code written around value set loading and access.  This includes fixes to resolving value set function as well as value set hierarchy functions.  This also contains fixes to long standing history load issues, some tree extension issues and simple search api problems.  We updated an outdated tracking policy artifact in this release as well — removing a couple of failing value sets that were placeholders for issues that should be resolved.  This allows continuous integration to be more accurate and precise without any expected failures that can be ignored.
