Does Alfresco have a changes API?

Dear alfresco communuty:

Does Alfresco have a full featured "Changes API?" I need something that can give me a list of all Added, Updated or Deleted documents since a given time. And it needs to also return documents where only permissions or metadata were changed, not just when the content was changed.

Does Alfresco have such an API?

This is how SOLR tracking works as well as other solutions that use polling, such as Apache ManifoldCF.

You might want to take a look at the SOLR web scripts and dig into their source to see how they work:

http://localhost:8080/alfresco/s/index/family/SOLR

If those don't meet your needs you could see if the CMIS getChanges API will work for you:

https://chemistry.apache.org/docs/cmis-samples/samples/changelog/index.html#retrieving-the-change-log

Finally, if neither of those do what you want, consider using an event-based approach and react to events when nodes are updated instead of polling for changes:

Hope those help,
