I have managed to run the first example, simpleCSV, on the web site and it appears to work but I am surprised because the dfdl schema doesn't look correct at all

The 'matrix' of numbers is defined as

Data:
Creator: NCSA
Date: Mon Feb 23 15:20:47 CST 2009
0,1,2,3,4,5,6,7,8,9
1,2,3,4,5,6,7,8,9,10
2,3,4,5,6,7,8,9,10,11
3,4,5,6,7,8,9,10,11,12
4,5,6,7,8,9,10,11,12,13
5,6,7,8,9,10,11,12,13,14
6,7,8,9,10,11,12,13,14,15
7,8,9,10,11,12,13,14,15,16
8,9,10,11,12,13,14,15,16,17
9,10,11,12,13,14,15,16,17,18

Schema
<schema xmlns="http://www.w3.org/2001/XMLSchema"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:dfdl="http://www.ogf.org/dfdl/dfdl-1.0"
targetNamespace="http://www.example.org/example1/">



<element name="matrix" type="matrixType"/>

<element name="table" type="SimpleTable"/>

<complexType name="SimpleTable">
<sequence>
<element name="hdrblock" type="header"/>
<element name="matrix" type="matrixType"/>
</sequence>
</complexType>

<complexType name="header">
<sequence>

<element name="Creator" type="xsd:string"
dfdl:terminator="%NL;" dfdl:initiator="Creator:"

dfdl:lengthKind="delimited"/>
<element name="Date" type="xsd:string"

</complexType>

<complexType name="matrixType">

<element name="cell" type="xsd:int" maxOccurs="unbounded"
dfdl:terminator="%NL;" dfdl:separator=","

dfdl:lengthKind="delimited"
dfdl:documentFinalTerminatorCanBeMissing="yes"/>
</sequence>
</complexType>
</element>
</sequence>
</complexType>

</schema>

but some of the dfdl properties on matrixType in particular are in the wrong place. I think it should be something like

<schema xmlns="http://www.w3.org/2001/XMLSchema"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:dfdl="http://www.ogf.org/dfdl/dfdl-1.0"
targetNamespace="http://www.example.org/example1/"
dfdl:documentFinalTerminatorCanBeMissing="yes">


<element name="matrix" type="matrixType"/>

<element name="table" type="SimpleTable"/>

<complexType name="SimpleTable">
<sequence>
<element name="hdrblock" type="header"/>
<element name="matrix" type="matrixType"/>
</sequence>
</complexType>

<complexType name="header">
<sequence>

<element name="Creator" type="xsd:string"
dfdl:terminator="%NL;" dfdl:initiator="Creator:"
dfdl:encoding="ASCII" dfdl:representation="text"
dfdl:lengthKind="delimited"/>
<element name="Date" type="xsd:string"
dfdl:terminator="%NL;" dfdl:initiator="Date:"
dfdl:encoding="ASCII" dfdl:representation="text"/>
</sequence>
</complexType>

<complexType name="matrixType">
<sequence>
<element name="row" maxOccurs="unbounded" >
<complexType>
<sequence dfdl:terminator="%NL;" dfdl:separator=","
dfdl:separatorPosition="infix" dfdl:separatorPolicy="require" >
<element name="cell" type="xsd:int" maxOccurs="unbounded"
dfdl:encoding="ASCII"
dfdl:representation="text"
dfdl:lengthKind="delimited"
/>
</sequence>
</complexType>
</element>
</sequence>
</complexType>
</schema>

There are also, of course, a lot of required properties (eg dfdl:lengthKind and dfdl:representation) missing from all the schema components but I assume that is due to the lack of property defaulting support.

FWIW, the Daffodil demo site is now running at its permanent URL:
http://daffodil.ncsa.uiuc.edu/As we work on Daffodil to bring it into compliance with the spec, we will update the parser on the site and keep a change log. I also have ideas for a much easier interface for the site, which I can develop once higher-priority fixes are complete. -- Joe Futrelle Cyberenvironments and Technologies National Center for Supercomputing Applications
