(smile) * More to come -- IPP Everywhere v1.1 PWG Last Call Q4 2019 / Q1 2020 -- IPP Everywhere Self Certification v1.1 PWG Last Call Q1 2020 -- IPP Everywhere Self Certification v1.0 - Update 4 Beta release 4 February 2020!
* IPP Authentication Methods v1.0 16 August 2019 -- https://ftp.pwg.org/pub/pwg/informational/bp-ippauth10-20190816-5199.10.pdf * IPP Job Extensions v2.0 16 August 2019 -- https://ftp.pwg.org/pub/pwg/candidates/cs-ippjobext20-20190816-5100.7.pdf * IPP System Service v1.0 - 22 November 2019 -- https://ftp.pwg.org/pub/pwg/candidates/cs-ippsystem10-20191122-5100.22.pdf
* Recent press releases -- 9 October 2019: Newly approved IPP specifications and Best Practices --- IPP Authentication Methods v1.0 --- IPP Job Extensions v2.0 --- IPP Document Object v1.1 --- PWG MFD Alerts v1.1 * Pending press releases -- Status of IPP Everywhere Program -- Recently approved 3D related PWG specifications and recently established 3D-related liaison relationships --- IPP 3D Printing Extensions v1.1 --- PWG Safe G-Code Subset for 3D Printing v1.0 -- IPP System Service v1.0
* Including Best Practices and Requirements documents in the numbering system -- Update to "pwg-namespace-policy.txt" in development -- Update to "ipp-registry-policy.txt" in development * Process v4.0 active development -- Prioritized for completion in 2020 * Original notion: Update existing Process 3.0 to merge in subsequently published PWG process documents -- pwg-policy-call-for-obj-last-call-formal-vote-draft-2.txt (draft) -- ipp-registry-policy-20191022.docx -- pwg-billing-policy-20141001.txt -- pwg-white-policy-20140505.txt -- pwg-charter-policy-20140407.txt -- pwg-prototype-policy-20121029.txt -- pwg-namespace-policy-20190823.docx (latest draft) * Revised notion: Refactor the Process document to describe the processes of the PWG to make them simple and obvious to the uninitiated reader: -- Job Descriptions for all PWG officers and other officials -- Proposing new work to the PWG -- Approving new work and assigning to a PWG work group -- PWG approval for various document types (whitepaper, standard, etc.)
* 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" will decouple 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.)
