[IPP] WS-discovery binding for IPP Everywhere

[Justin Hutchings]

Hi Michael,
I'm sorry, I don't know how to do that. The ippe:Print is a QName, but I frankly have no idea how to build an XSD that establishes a well defined set of QNames.

Perhaps someone else in the group has more expertise in this space? There's only 1 QName to document, AFAIK.

Thanks
Justin

Justin,

Can you provide a schema file that I can put up on the PWG web site?  The namespace should be "http://www.pwg.org/schemas/2012/4/ipp-everywhere" to match the form we use for Semantic Model schema.

Thanks!

All,
Per the discussion at this week's face to face, I mocked up an example of how to do discovery of an IPP endpoint using ws-discovery. Since WS-discovery doesn't especially care what matching semantic model is used, I would propose that we just reuse the LDAP model to simplify the development experience for people. The only unique descriptions we'll need are to establish some keywords that describe the different IPP protocols, like IPP Everywhere print, scan, fax, etc. That should be pretty trivial, as we just need to name them and publish a schema.

How does this look?

Thanks!
Justin
