Hello all, I've implemented a basic "Hello World" style example program using Agile Delta's EXI implementaion with Daffodil:
https://github.com/OpenDFDL/examples/pull/27 There is one issue in particular that I wanted to bring up. Right now it cannot do schema aware EXI as it can't always resolve schemas correctly by default. The Agile Delta SDK does have a SchemaResolver interface that would be pretty straightforward to impelment using Daffodil's DFDLCatalogResolver. However, the DFDLCatalogResolver is not exposed to the Java API (which is what this example is using). It seems to me that the right thing to do would be to expose the DFDLCatalogResolver to the Java API but figured it should be brought up for general discussion. DFDLCatalogResolver is implementing a Java interface under the hood (org.xml.sax.EntityResolver) and we expose most of the other SAX interfaces that Daffodil implements anyways. DFDLCatalogResolver was also needed when implementing the Exificient support in the Daffodil Main program, but since that is written in Scala and is part of Daffodil itself, it wasn't a big deal to just import the DFDLCatalogResolver class. Please let me know what you think the correct path forward is. I'll take feedback either in this thread or in the pull request linked above. Josh Adams
