First Release of DFDL4S Parser Library
Dear Steve,
1) I can confirm that we have used version 207 of the
DFDL as reference.
2) The DFDL4S implementation and the delta between the
Core DFDL spec and what has been
implemented is documented in
3) Schemas can be easily exported by the S2G app, but
I attach some for reference (they are all inside the jar)
3) We can have a teleconf Tomorrow at 16:00 CET if you
want, Should I set up a Webex to share the screen ?
Regards
Michele

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)
?

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.
