Right, let's keep this to collecting requirements:
+1. Ok, so it seems we're all pretty much in agreement that metadata extraction and
indexing should happen on the server side and not on the client. As I said before, this
is good. Simple clients, support for re-indexing, support for changes in indexing
characteristics, and the ability to save the world from AIDS.
This puts a requirement on an efficient and portable serialisation format. Again, +1 to
starting with defining what we need. Good start below, Sanne.
- being able to upgrade the server without losing data
- being able to change the (soft) schema on the server
- read/write fields from different languages
- deal with multi-version control of values (i.e. being able to read
an older value through an evoluted schema, doing comparisons of same
value even if it was stored using different schema generations)
I'd add:
* Support for fast and easy translation to/from object model in high level language of
choice (i.e., not manual parsing! Maybe some form of tooling, like a Maven plugin, to
generate "IDL"-esque format)
* Serialisation efficiency (size and speed) should be considered
And in addition, I'd also list out existing technologies that fulfil some or all of
these requirements that we can consider, look at extending, etc.
