Dear Michele
Good to hear from you. Thank you for
letting me know about the latest developments with S2G Data Viewer.
I am sure the DFDL Working Group would
be interested in a demo of S2G. What is your availability on Tuesdays at
4pm-5pm UK?
Meantime do you have a document that
you could send which summarises which features of the DFDL language you
have used, and some example schemas?
Please note that the DFDL 1.0 specification
was re-published in October 2014, replacing and obsoleting the version
from January 2011. Does S2G comply with the October 2014 version
(https://www.ogf.org/documents/GFD.207.pdf)
?

[DFDL]: First
Release of DFDL4S Parser Library
Dear Steve,
we talked some time ago when we presented the tool we
developed at ESA
to inspect satellite TM and which made use of DFDL description
for the binary data
and we have included a number of your comments at the
time.
Since then we have further evolved the tool (called S2G
Data Viewer) and produced as well a
standalone version of a Java library which performs the
function of extracting data field from binary data
based on a DFDL description. This library (called DFDL4S
i.e. DFDL for Space) is now available
to anybody interested. It implements only the subset of
the Core capability that we need but I think
it might be nevertheless interesting for the DFDL community.
In future we plan to expand to write capability the same
library so user can serialise their data as
per DFDL description and generate realistically looking
(simulated) satellite data.
The application and the library are available for download
at http:eop-cfi.esa.int
If there is interest we could arrange a short demo of
the app (using webex) or I couldd ask
the developer to show the command line test of the DFDL4S
library.
We are very happy/willing to share results/code/etc.
Best Regards
PS we are currently thinking to build “transformation”
that can ingest different type of descriptive
representation and generate the corresponding DFDL schemas.
