We are currently in the process of developing a system that maintains the health records of patients. A terminology registry with look ups is an important part of our system. We are exploring the possibility of using ApelonDTS as the implementation of the terminology registry. We are planning to integrate the various parts of our system through atom feeds. We might have to cache parts of the knowledge base at various locations. For the caching to work, we need a mechanism to listen to changes to the concept.

We would like to know,

1. Is there an existing mechanism through which I could hook into the updates to a concept and publish an event to the feed.
2. If it s not possible, what is the mechanism you would suggest to implement the cache.

PS

If it is currently not possible to hook into updates and should you like to develop the hook, we could help out with the same.

Currently, DTS provides a client-side "listener" mechanism by which an application, such as the DTS Editor, can receive notifications for a variety of update actions taken in the same application. This allows different panels in the Editor, for example, to refresh after concept modifications, etc.



What you are describing, however, requires a server-based notification mechanism to support a broader subscribe/publish use case. This capability is on our roadmap and we would be interested in better understanding your requirements and/or discussing possible joint development activities. If you'd like to discuss further, drop a note to info@apelon.com and we'll get back to you.

Yes, it looks like we would need a server side mechanism for the same. Will try to come up with some workflow diagrams that will help you better understand our requirements.

In the mean time there are a couple of small improvements that I could do with the packaging (especially on linux) like correcting the paths to utility files. If you could point me to the code, I could make changes and send you a patch?
