RDF serialization and modules

Hi all,
Apologies for not making recent meetings, unfortunately I have to teach
on Monday mornings.
I have looked at the repository and added a version of the RDF
serialization as a pull request here:
https://github.com/oasis-tcs/lexidma/pull/16
(I note that the build checks have failed, but this seems to be because
the build checks are incorrectly configured).
I also saw that my contributions to the standard, in particular the
etymology module seem to have been deleted. Perhaps someone could
explain why this has happened and restore them as they were already in
the correct Docbook format.
I will read through the spec soon and provide some detailed comments.  Regards,  John
