(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
* PWG MFD Alerts v1.1 – 12 April 2019 -- https://ftp.pwg.org/pub/pwg/candidates/cs-pwgmfdalerts11-20190412-5017.3.pdf * IPP Document Object v1.1 – 21 May 2019 -- https://ftp.pwg.org/pub/pwg/candidates/cs-ippdocobject11-20190521-5100.5.pdf * 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
* Recent press releases -- 18 June 2019: PWG / 3MF Consortium Liaison Agreement Establishment -- 22 May 2019: Printer Working Group (PWG) to Address 3D Printing Standards at 21 May 2019 RAPID + TCT Additive Manufacturing Event -- 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 v1.0ACTION: 11/20/19 - Smith / Ira to ping Anne Price to write drafts for IPP Everywhere 1.1 and Release 4 of IPP Everywhere 1.0 tools and IPP 3D Printing in December 2019 to be ready for January (avoiding CES 2020 overload)
* 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 still a work in progress
* 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
* Original notion: Update existing Process 3.0 to merge in subsequently published PWG policy documents -- pwg-policy-call-for-obj-last-call-formal-vote-draft-2.txt (draft) - updating -- ipp-registry-policy-20191121.docx (latest draft) - updating -- 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) - updating * Revised notion: Refactor the Process document to describe the processes of the PWG to make them simple and obvious to the uninitiated reader: -- Proposing new work to the PWG -- Approving new work and assigning to a PWG work group -- PWG approval for various document types --- Whitepaper --- Standards-track --- etc.
* 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) -- Collaborative offline review could accelerate the PWG standards development process * Future 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
* 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.)
