The following is the summary of the proposal: To improve the ability to debug and maintain UIMA components, we propose to add the ability to log the updates to the CAS and the Index Repository as follows: - track which Analysis Engines (AEs) created or modified the feature structures in a CA - track the operations (add and delete) by each AE to index feature structures For the "user interface" part of the tool, I have posted the initial proposal<http://cwiki.apache.org/UIMA/cas-viewer-extension-for-provenance-tracking-of-uima-cas-content.html>for further discussions in our Wiki. This Wiki page includes the screen mock-ups as an extension to the user interface of the CAS Viewer. Please take a look and comment/discuss on the proposal. Regards, Tong
