Request for Step Proposals (Deadline: May 11)

Dear XProc Community,

This is a reminder that we will meet in London on June 10+11, right 
after Markup UK. Watch this space for updates: 
https://github.com/xproc/Workshop-2019-06

The meeting will be mostly about steps, and we are planning to finalize 
the step specs shortly after the meeting.

This page provides links to the additional step specifications: 
http://spec.xproc.org/
Some of them are placeholders at the moment, some might still show the 
XProc 1.0 step signatures.

If you have a proposal for an additional step or if you think there 
should be changes to the current step spec drafts, please let us know 
until May 11, preferably here: https://github.com/xproc/3.0-steps/issues
Please do check first whether the topic has already been discussed in 
existing issues (also in closed ones).

We are looking for meaningful steps for processing text and JSON 
documents. The standard step p:cast-content-type 
(http://spec.xproc.org/master/head/steps/#c.cast-content-type) already 
serves as a generic conversion utility between media types. So please do 
also have a look at what the standard step library already provides. If 
there are multiple useful output formats (for example when converting 
between XML and JSON), an XProc processor may provide parameters for 
selecting specific input/output mappings. You can inform the 
implementors about which library you’d suggest for converting, for 
example, from image/svg+xml to image/png, but since this is 
implementation-defined we don’t need to specify the possible conversions 
and their parameters in one of the step specs.

We are also looking for RDF steps. Hans-Jürgen Rennau suggested that we 
support SPARQL for querying and SHACL for validation. Geert Bormans is 
currently collecting requirements for RDF steps. Please get in touch 
with him a couple days before May 11 so that he can consolidate the 
proposals.

The validation steps and the proposed validation reporting language XVRL 
will be my domain. There will be an update to the steps and to XVRL 
(https://github.com/xproc/xvrl) in the next couple of days (in April, 
definitely). I’m going to solicit comments until approx. May 15.

We are looking forward to receiving your proposals until (and including) 
May 11 and/or to meeting you in person in London.
