Dear Michele

I can have a call at 16:00 CET tomorrow but if you want other people from DFDL Working Group to attend then it should be at 16:00 UK (GMT+1 = BST). This is an hour behind CET.

Please email webex details to dfdl-wg@ogf.org.

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 https://www.ogf.org/documents/GFD.207.pdf) ?

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 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.
