We have released version 1.10 of the UMBEL (Upper Mapping and Binding 
Exchange Layer) reference concept ontology [1]. This new release is in 
preparation for a series of subsequent releases planned over the next 
few months that will extend the functionality of the system in important 
ways.

This is the first UMBEL version to be created and loaded from scratch 
using a new Clojure scripting framework. Fred Giasson describes these 
scripts and highlights some of the new functionality in a separate blog 
post [2].

Besides this new processing framework, here are some of the key changes 
at a high level made in this new version:

* Reconciliation with the parent OpenCyc concepts
* Added reference concept definitions where missing
* Added additional altLabels (to the semsets) in many cases
* Checked graph integrity for relationships between concepts
* Reviewed and corrected prefLabels to make them unique (for more 
usefulness in autocompletion)
* Checked assignments of all reference concepts to a parent SuperType
* Reviewed SuperType assignment inconsistencies and removed some 
disjoint assertions
* Updated mappings with OpenCyc (version 4.0, dated October 12, 2012), 
GeoNames (version 3.1, dated October 29, 2012), schema.org (version 1.9, 
dated August 19, 2014) and the DBpedia ontology (version 3.9, retrieved 
August 18, 2014).

The resulting mappings now are:

* 26,091 Reference Concepts in UMBEL Core
* 1,925 Reference Concepts in UMBEL Geo
* 27,691 links between OpenCyc and UMBEL (which includes Core & Geo)
* 754 links between Schema.org classes and UMBEL
* 688 links between Geonames.org classes and UMBEL
* 682 links between the DBpedia ontology classes and UMBEL.

These changes have also resulted in some improvements to the umbel.org 
Web site and its Web services [1], as more fully described by Fred. The 
updated ontologies and mappings may be found at the UMBEL GitHub site [3].

Please feel free to address any questions or comments to the UMBEL 
mailing list [4].

Thanks!
