RDF serialization and modules

[John McCrae <john.mccrae@insight-centre.org>]

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
