I'm working with a system that requires directories and
directory-modified timestamps (for a webDAV-like browsing feature), but
have found that automatic directory creation introduces unacceptable
lock contention during bulk updates, so I am looking into managing the
directory creation and timestamp updates manually.
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";>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";>
<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?
