[Geotools-devel] GTXML code generation & data sources

[Ákos M. <ak...@ma...>]

Hi,

I'm (still) trying to create a Data Store that can handle an XML file
format defined by an XML Schema, which is based on GML. The XML schema
itself is quite complex, therefore I'd do as much code generation based
on the schema as possible. I do have JAXB properly generating an API
based on the XML Schema I have, which is AIXM.

I also looked at the GTXML documentation & samples, and I understand
that this can also generate code stubs that would help me to parse data
defined by the XML Schema using GeoTools.

But a link is missing for me still. If I want to create a Data Store, I
have to describe the data 'schema', the 'feature types', etc. and simply
I don't see the link here between GTXML and the code generated by the
gt-xml code generator from my XML Schema, and the (generated) helpers
that would save me from manually creating FeatureType / ComplexType
objects that describe the nature of data being handled, which would be
based on the XML Schema. such FeatureTypes have to returned by the Data
Store / Feature Source.

Is there an example somewhere that would demonstrate such a use case
'all the way'? that is, based on an XML Schema (.xsd) file, it would
show how one generates an object hierarchy representing the data from
the XSD, including a data store that actually handles such data?

best regards,


Akos
