* Moving to new web hosting facilities -- Started in 2018 -- Slow progress because the shift requires a shift in how the various services are managed; not just a simple "lift and drop" --- Static Website --- Dynamic Website ---- IPP Everywhere Certification Portal ---- Blog / article / news reporting ---- Document errata issue reporting system --- FTP Site --- Mailing lists -- Update to "ipp-registry-policy.txt" decouples process from reflector archives
* Current Toolset
-- Microsoft Word for specifications
-- Microsoft PowerPoint for presentations
-- Plain text for policy documents
* Why change?
-- Authoring specifications with Word can be a very manual and error-prone process
(e.g., references are awkward)
-- Check with similar groups and see if there are things we can adopt
* Possible alternatives
-- LibreOffice 6 for specifications and presentations
--- Smith "experimented" with this 2017-2018
---- Conclusion: painful...
-- Metanorma: Asciidoc / Asciidoctor extension for writing specifications
--- In limited use in IETF and other SDOs
--- Ira and Mike have been investigating; some undesirable qualities
--- Smith is experimenting with using Asciidoc / Asciidoctor for recent policy
document drafts
* Purpose:
-- A document that describes the PWG's core tenets and design principles that guide
the design and creation of its IPP, Semantic Model, MIBs, and other technologies
* Scope / Topics to be Covered:
-- IPP
--- Late binding principle
--- Intent vs. process for Job fidelity
--- Value of separating Job attributes from Document content
--- IPP attribute types and design patterns
---- Printer Status vs. Printer Description
---- xxx / xxx-supported / xxx-default vs. xxx / xxx-configured / xxx-supported
---- Collections vs. textual encoding of MIB sequences ("printer-finisher")
-- Semantic Model
--- Creates comprehensible view of the elements in an Imaging System, allowing better
communication with other standards organizations dealing with related matters
--- Presents the basic features necessary in communicating with Imaging Services,
independent of the protocols used in that communication
--- Allows exploitation of the inherent parallelism between different types of Imaging
Services (Print, Scan, Fax, etc.)
