Hi David. I've cced this to the development list, so everyone can read 
about what you've been up to.

hmm. Just a comment here: you really should avoid setting up a class 
hierarchy if you can avoid it - the parsing overhead from creating lots 
of objects is quite considerable. Jalview has a quite extensive 
annotation datamodel, which will work for non-hierarchical sequence 
features - but not for more complex compound/hierarchical features 
(http://issues.jalview.org/browse/JAL-1191). For the full gory details 
of this type of annotation, you need to read the documentation here:
http://www.insdc.org/files/feature_table.html#2

however - don't start hacking on this until we talk - there are some 
very good examples of how to implement complex/compound feature 
datamodels, and I'd prefer it if we first analyse those and work out 
which one fits Jalview's needs best.

eek!  We already have the castor source generation machinery bundled 
with Jalview. By using a maven plugin, you risk breaking compatibility 
with the bundled version of castor, which is NOT good. If you must use 
castor XSD->Java, then take a look at the 'castorbinding' task in 
build.xml - this already includes a set of XSDs that create java 
bindings for the Jalview project and colourscheme files which are 
critical for the jalview desktop.

You should also bear in mind that currrently, fileformats dependent on 
classes autogenerated with castor will not be available in the applet, 
since XML parsing libraries are considered too heavyweight to ship to 
the browser. This is the most significant reason for not using 
XSD->Java object mapping, but there are other reasons for avoiding it: 
e.g. when working with large XML files, stream XML processing avoids 
the memory and object creation overhead incurred by creating an object 
representation of elements in the document.

Re understanding Jalview's datamodel.. I know an ER diagram would help, 
but it will only get you so far, since you also need to think about how 
the data that you are trying to import into Jalview is structured 
(remember, the XML format may not necessarily correspond to the way 
that the data might be most usefully be handled in Jalview).

We are going to talk through this on our next google hangout.

You are quite right in recognising that Jalview would benefit from 
being part of an information integration framework. In fact, Jalview 
already includes a couple. VAMSAS is a prototype data and application 
integration framework for bioinformatics data that I developed in 
collaboration with some other groups. DAS is a much more widespread 
data integration framework based on XML/REST services that has been 
around since 2001 (http://www.biodas.org/wiki/Main_Page). It was 
developed for sequences and sequence features on genomes, but has been 
adapted to work with other types of data.

As you might imagine, I'm interested in integration frameworks, and 
would be interested discussing ideas with you colleague, though I 
should say now that I already have enough deadlines for this year!

Done. Translations component is here.
