Whew, good. Remember, like I said, it's very good at *reading* the xmp metadata now, but still has some issues writing that I'm looking into.
Another thing to note: For many of the "namespaces schemas", I found documentation about the tags and put those in my table so it gets the types correct. But there were many instances of metadata I saw in your file whose names were not in the official documentation for those schema, and of course in any file it may come across a schema I haven't seen and didn't know to put in the table. In those cases, it will put the unknown metadata into the ImageSpec attributes, but it will just make it a string (it's hard to find a heuristic for what the type is supposed to be without guessing wrong some of the time). So depending on what you're looking for as you root through the metadata, your app's logic should be prepared for some of them to unexpectedly be strings, and do whatever conversion is necessary on your end. Of course, if you *know* a particular name/type that will pop up despite not being in the schema docs, I'm happy to add it to the table. > On Apr 26, 2017, at 9:58 AM, Chris Bennett <[email protected]> > wrote: > > Hey Larry, > > Thanks for the patch!
