#opfoag — Public Fediverse posts

@bitsgalore I’m terrified I will miss my own presentation. #OPFOAG

@marhop ended up being too tired after the #OPFOAG yesterday .... i gave it a quick try and then fell asleep over it. will have to catch up on the train ride today.

A l'#OPFOAG hier, bribe de conversation volée : "si je n'ai plus de cheveux sur le crâne, c'est à cause de #PDF." #wtfpdf
Ça donne le ton. Sur le PDF, on a un énorme chantier à mener.

#OPFOAG Thomas Ledoux advocates for a standard #schematron edition tool to enforce institutional policies on #JHOVE, #veraPDF & #jpylyzer outputs.

#OPFOAG #OPF considers creating a new #JHOVE module for validating spreadsheet.

#OPFOAG

@bitsgalore is giving a quick introduction in his jpylyzer tool now - the recently release v2.1 will be the last one using Python 2.
If you don't know the tool, check it out here:

#OPFOAG

JHOVE 1.28 release candidate will be out this month (i.e., Dec 2022)
--> public release should be out in the last week of jan 2023 (depending on feedback for release candidate)

#OPFOAG Remember that when trying to validate / characterize a file with #JHOVE, you should specify the module to use. Otherwise, if the file does not comply with its specification, it will be considered as a plain octet stream...

#OPFOAG
Eh, les personnes intéressées par la préservation numérique : #JHOVE existe lui aussi en version en ligne pour des analyses unitaires...

#OPFOAG

Carl is talking about "The Heroics of Gary McGath! and how OPF took on JHOVE when Gary couldn't maintain it anymore. I think the history of JHOVE is such a nice use case for open software previously maintained by one person while having a large user base, which was then picked up by a non-profit organization where it now has many contributors and an even larger user base

#OPFOAG

JHOVE is available in four forms:
- cli: used by researched & practitioners, soon with Docker image
- GUI: general users wanting to try JHOVE
- API: used by devs embedding JHOVE into their own projects
- REST: application with accompanying docker image

"Levels of conformance

Format validation conformance is determined at 3 levels: well-formedness, validity and consistency:
- A digital object is well-formed if it meets the purely syntactic requirements for its format

- an object is valid if it is well-formed & meets higher-level semantic requirements for format validity

- an object is consistent if it's valid & its internally exttracted representation information is consistent with externally supplied representation information"
