Re: [Exist-development] Metadata in eXist

[Patrick B. <pat...@jo...>]

So, it seems like we're fairly agreed that a new axis is not the way to go.
I would tend to agree that is the right decision. So the only question left
is whether to use key/value or xml fragments. I like Wolfgang's method of
accessing metadata, it seems very consistent and intuitive. Unless I'm
missing something, I'm still having a hard time seeing value in choosing
key/value over xml fragment. Since under Wolfgang's suggestion anyone who
wanted a key/value type metadata set could simply access them as

metadata("/db/doc.xml")/keyOne
metadata("/db/doc.xml")/keyTwo


This may not allow us to store binary data natively in metadata fields. But
I would contend that in 99% of cases metadata is being used to aid in
searching for or classifying another resource in the database.


As a side note. I'm planning to begin working on implementing this around
the 2nd week in August.

Cheers,

Patrick
