Doug Cutting commented on AVRO-659:
-----------------------------------
JSON-format schemas should be self-contained, since they must fully describe
binary data.
However Avro IDL supports file inclusion (AVRO-495). There was discussion in
that issue about searching a set of directories for included files. I
suggested we follow the C convention, where double-quoted imports search the
application's path and angle-bracketed imports search a "system" path. Would
this address the need you describe?
> Portable specification of the location of schema and protocol files

> Avro doesn't require code generation, which is great. However, if you want to
> use a protocol or a schema, your code needs to know where to find it. When
> your code is ported to new systems, the protocol or schema file must be
> placed in the same place as on the previous system for things to work
> correctly.
> For importing modules in a portable fashion, Python provides a default set of
> places it will look for modules and an environment variable called PYTHONPATH
> that programs can use to override these defaults. It may be useful to explore
> similar constructs for Avro implementations that don't do code generation.
