*** Mopria (Smith Kennedy) - see Plenary slides

* Mopria liaison to PWG : Michael Rhines (Qualcomm)


* New 2-year liaison agreement signed 3 April 2020


* PWG Chair to present at the November 2020 Mopria Member Meeting

*** INCITS TC (Paul Tykodi) - see Plenary slides

* PWG / INCITS TC Liaison established 15 April 2020


* Paul Tykodi will represent the PWG in INCITS TC activities


* INCITS Digital Manufacturing Technical Committee
-- The IEEE-ISTO Printer Working Group has established a liaison relationship with 
   INCITS Digital Manufacturing Technical Committee 
   https://www.businesswire.com/news/home/20200505006085/en/InterNational-Committee-Information-Technology-Standards-INCITS-IEEEISTO.

--- The INCITS Digital Manufacturing Technical Committee meets monthly (third Tuesday of the 
    month from 12pm to 2pm US EDT)


-- The INCITS TC has asked Paul Tykodi to determine whether PWG members would potentially be 
   willing to participate in two different focused discussions to be held in 15 September 2020 
   and 20 October 2020 INCITS meetings:

--- 15 September 2020 – Discuss whether 3D PDF could possibly be considered as a candidate for 
    a future 3D CAD Data Transfer Standard

--- 20 October 2020 – Discuss the possible benefits in creating cybersecurity Common Criteria 
    Protection Profiles for 3D printers


-- The INCITS Digital Manufacturing TC is the current US TAG for ISO/IEC JTC 1 WG 12 
   (3D Printing and Scanning). The Printer Working Group is monitoring the activities 
   of JTC 1 WG 12 via the INCITS liaison relationship.

*** 3D / Additive Manufacturing Liaisons (Paul Tykodi) - see Plenary slides

* America Makes & ANSI Additive Manufacturing Standardization Collaborative (AMSC)
-- https://www.ansi.org/standards_activities/standards_boards_panels/amsc/Default?menuid=3

-- The IEEE-ISTO Printer Working Group is participating in the AMSC initiative


* ASTM Committee F42 on Additive Manufacturing Technologies 
-- https://www.astm.org/COMMITTEE/F42.htm

-- The IEEE-ISTO Printer Working Group standardization efforts intersect with the 
   activities of at least two ASTM F42 subcommittees:

--- Subcommittee F42.08 Data

--- Subcommittee F42.91 Terminology

-- The purpose of the liaison agreement is to keep the standardization efforts of 
   ASTM F42 and the IEEE-ISTO PWG synchronized in areas where both organizations 
   are actively working.

* 3MF Consortium
-- https://www.3mf.io

*** Possible Future 3D / Additive Manufacturing Liaisons (Paul Tykodi) - see Plenary slides

* PDF Association - https://www.pdfa.org/
-- Paul Tykodi has been asked by the 3D PDF Consortium and PDF Association to chair an ad hoc 
   for ISO TC171 SC2.  The purpose of the ad hoc is to investigate how PDF files support 3D 
   content stored within them and to make possible recommendations for enhancing future ISO 
   32000 (PDF standard) support for metadata describing 3D content placed into a PDF file.

-- The PDF Association has taken over the role of US TAG for ISO TC171 SC2 from the 3D PDF 
   Consortium.  Paul Tykodi was asked to join the PDF Consortium as a member, in order to be 
   allowed to create a PDF Association liaison working group, in support of the information 
   gathering needs of the ad hoc.  Once the ad hoc completes its efforts, the longer-term 
   strategy for the PWG would likely be to create a liaison with the PDF Association.


* ISO TC171 SC2 WG12 (PDF Metadata) - https://www.iso.org/committee/53674.html
-- The IEEE-ISTO Printer Working Group has been asked to form a Category C liaison with ISO 
   TC171 SC2 in order to participate in a new foundational metadata for 3D content contained 
   in a PDF file standardization effort to be undertaken by WG12.  This request is currently 
   on hold pending the outcome of the research to be performed by the ad hoc described above.
