I think if you want to maintain these yourself, you should not use the system maintained properties; instead, make up some of your own that do the equivalent things.
That being said, have you tried leaving directory creation at automatic, but turning off maintain last modified and maintain directory last modified? Depending upon how deep your directory hierarchy is, this might not cause too much overhead. I would recommend trying that, and then just add a dateTime property (or element in the document if you prefer, allowing you to not have to create a property fragment) to track whatever you want about the last modified (based on your app requirements). I think that might work well, especially if your hierarchy does not not have millions of directories. See how it works and let us know. -Danny From: [email protected] [mailto:[email protected]] On Behalf Of Keith L.

I have one question, and one strange observation - maybe a bug. I'm working with 7.0-2.3. First the question: how should I update the prop:last-modified property? Updating it explicitly raises an error: XDMP-ARG: xdmp:document-set-property("/books/", <prop:last-modified xmlns:prop="http://marklogic.com/xdmp/property";<https://urldefense.proofpoint.com/v1/url?u=http://marklogic.com/xdmp/property&k=wlPCrglRP6kzT4RbABWMaw%3D%3D%0A&r=2FOxwjXkcRFP9Zb5gsGqutGbMyYaH6V5O1y2qyDOE%2Bw%3D%0A&m=tMQwNzleMcPFHrHVywsz7LShGCB7BV0fr4nwOoRO9yE%3D%0A&s=b129b0afdc261f273e05e156d512fac53273fae49be30e4e6423deb66508ad09>>2014-05-22T15:53:46.724003+02:00</prop:last-modified>) -- Invalid argument even though I have "maintain directory last modified" set to false (and directory creation = manual). I do have maintain last modified set to true, so I expect that is happening automatically on directory creation - OK, but in that instance how would I update the directory modified time when inserting or deleting documents in the directory? I tried adding a dummy property using xdmp:set-property, and that does seem to update the timestamp, but I don't really want to do that if I don't have to, of course. Perhaps I could delete and then recreate the directory properties document, but that doesn't seem great either. Any other ideas? Now the weird observation. It seems that every time I modify the directory properties document, it gets another <prop:directory /> property node! Currently I have: <prop:properties xmlns:prop="http://marklogic.com/xdmp/property";<https://urldefense.proofpoint.com/v1/url?u=http://marklogic.com/xdmp/property&k=wlPCrglRP6kzT4RbABWMaw%3D%3D%0A&r=2FOxwjXkcRFP9Zb5gsGqutGbMyYaH6V5O1y2qyDOE%2Bw%3D%0A&m=tMQwNzleMcPFHrHVywsz7LShGCB7BV0fr4nwOoRO9yE%3D%0A&s=b129b0afdc261f273e05e156d512fac53273fae49be30e4e6423deb66508ad09>> <prop:directory/> <prop:directory/> <prop:directory/> <prop:directory/> <prop:directory/> <prop:directory/> <prop:directory/> <prop:directory/> <prop:directory/> <prop:directory/> <prop:last-modified>2014-05-22T15:47:37+02:00</prop:last-modified> </prop:properties> I thought that properties documents maintained a map with unique keys? -Mike _______________________________________________ General mailing list [email protected]<mailto:[email protected]> http://developer.marklogic.com/mailman/listinfo/general<https://urldefense.proofpoint.com/v1/url?u=http://developer.marklogic.com/mailman/listinfo/general&k=wlPCrglRP6kzT4RbABWMaw%3D%3D%0A&r=2FOxwjXkcRFP9Zb5gsGqutGbMyYaH6V5O1y2qyDOE%2Bw%3D%0A&m=tMQwNzleMcPFHrHVywsz7LShGCB7BV0fr4nwOoRO9yE%3D%0A&s=c9cb9dbd161260f93e52fe3901e1bb716460a6fcc74f86cb436db69aa2cd554c> NOTICE: This email message is for the sole use of the intended recipient(s) and may contain confidential and privileged information.
