Topics What is ISO 19165-2? Background Status Next Steps

ISO 19165-2 Title - Geographic information -- Preservation of digital data and metadata -- Part 2: Content specifications for Earth observation data and derived digital products Submitted New Work Item Proposal (NWIP) in 2016 NWIP approved – August 2017 Development has been in progress

Background (1 of 2) Importance of preservation of data and metadata for reusability, understandability and ideally reproducibility has been recognized by a large number of organizations ISO 19165-1 – Geographic information -- Preservation of digital data and metadata -- Part 1: Fundamentals – most recent standard for this Ramapriyan participated in Project Team led by Wolfgang Kresse “specific content items needed to preserve the full provenance and context of the data and associated metadata depend on the needs of the designated user community and types of datasets (e.g., maps, remotely sensed data from satellites and airborne instruments, physical samples). Follow-up parts to this standard may be developed detailing content items appropriate to individual disciplines” (section 7.3.1; ISO 19165-1)

Background (2 of2) Basis for ISO 19165-2 US – NASA/NOAA/ESIP – Provenance and Context Contents – listing Europe (ESA) – Long-Term Data Preservation (LTDP) Program documents US – NASA – Earth Science Data Preservation Content Specifications CEOS/WGISS - Earth Observation Preserved Data Set Content (PDSC)

Steps in Arriving at ISO Standard 00 – Preliminary 10 – Proposal – Approval through international balloting; Project Team members (experts from participating member countries) named to form Project Team (PT) (2017-08-16) 20 – Preparatory – New project is registered with Technical Committee (TC 211); (2017-08-16) 30 – Committee - CD registered; ballot initiated and closed; comments handled; CD approved for registration as Draft International Standard (DIS) (2019-02-17; 23-Yes, 0-No, 14-Abstain; 47 comments from 5 members – 17 editorial comments) 40 – Enquiry - DIS registered; ballot initiated and closed; comments handled; DIS approved for registration as Final Draft International Standard (FDIS) 40.00 - DIS registered (2019-07-02) 40.20 - DIS ballot initiated (2019-09-03) 40.60 – Close of voting (2019-11-25) 50 – Approval – FDIS registered for formal approval; ballot initiated and closed; FDIS approved for publication 60 – Publication – International standard published Green = Done

Sample Comments Primarily spaceborne even though scope claims to be more general – included some wording about airborne and in situ Has this been adopted by missions/projects? Gave NASA and ESA examples Raw data preservation should be mentioned – it is Include commercial and public communities in addition to science communities – included wording to cover them Clarify how this standard relates to ISO 19115-1, 19115-2, 19157, etc. – an annex to the standard does this Introduction should clarify: target audience, mission sizes covered, handling proprietary data, time-span covered, etc. - Added words to do this Clarify which items in content tables are mandatory – all items are recommended (none mandatory) Specific comments to add words to tables to accommodate airborne and in situ observations – included Note: Comments are summarized and paraphrased. Summarized responses are shown in green
