MediaConchFirstPass display option

No description provided.

Oo la la

[ablwr]

Yes! Tested all of these and look good to me. 👍

What is the purpose of MediaConchFirstPass.xsl?
It is not clear, and we are missing a "description" block.

[dericed]

It is for some characterization, but the policy is set up differently. It would be like:

<policy type="or" name="categorize these files">
 <policy type="and" name="Final Cut Capture">...</policy>
 <policy type="and" name="Camera Recording">...</policy>
 <policy type="and" name="Final Cut Export">...</policy>
 <policy type="and" name="Unknown File">...</policy>
</policy>

output would be:

filename1,Final Cut Capture
filename2,Unknown file
filename3,Camera Recording
filename4,Camera Recording

[JeromeMartinez]

I think MediaConchFirstPass should have a more relevant name. Not sure of which one, but here this is not clear.

[dericed]

FirstPass is meaning First Passing sub-policy or rule, but sure the naming could be improved. @ablwr?

[ablwr]

FirstToPass or QuickPass? Although unsure if it is actually much 'quicker'...

It seems like a FirstFail would be more useful?

[JeromeMartinez]

It is not quicker, so -1 for it.
FirstToPass: First what? --> FirstRuleToPass? (even if "Rule" is technically not correct because it is sub-policy or rule, the idea is there)

[dericed]

Does the user interact with the file name? I don't think CSV and First2Pass make much sense in the GUI where a report is viewed for a single record at a time. But how should these be in the CLI?

MediaConchCSV

• mediaconch -p policy.xml -fc some.mov files.mkv > yay.csv

MediaConchSimple

• mediaconch -p policy.xml -fs some.mov files.mkv

For scalability perhaps we should have long names as alias.

• -fx = --format xml = --format x
  etc

[ablwr]

-fx == --format=xml (which already exists)
-fc == --format=csv
-fs == --format=simple ?

[ablwr]

But what is the use case for FirstPass (to be renamed or not)?

[dericed]

todo: documentation, but generally the idea is to categorize media with a set of top-level policies and report on the first matching one. Some top level policies to detect if it is final cut capture, then another for media express capture, an access file, a mezzanine, etc. Then if you have a large set of random files this policy would group them by a type.

[ablwr]

I see. Contingent on this very specific use case of the first policy being the most important and set up in this particular way so that it may direct files out accordingly.

[dericed]

A bit inspired by the archivematica FPR as they have to categorize files and act according to that. The semantics are a bit off in this case though as pass/fail doesn't seem as appropriate, but it's more like match/not-match.

[JeromeMartinez]

From my point of view FirstPass is too much specific (and looks like an hack :) ), and should not be in the default installation, but should go in a "public display" page (@GuillaumeRoques will like the idea ;-) ).

Each display has some concerns (e.g. CSV output would not work well when we get 2 implementation checkers and 2 formats are in the list of parsed), I suggest to open 1 PR per display in order to not mix discussions.

[dericed]

Right, csv presumes the values of the first implementation check for each subsequent file. I could restrict it to Matroska. I can split the PR tonight.

[JeromeMartinez]

CSV and Simple are added (#522, #523, #524).

I let this one open for discussion about MediaConchFirstPass.xsl.
Issue:

• looks like a (good) hack, maybe not for general availability but for a public display page. In the meanwhile it could be used by sending the XSL to the interested people.
• Shouldn't we ad somewhere a description, with some indication about the purpose of the XSL? I am afraid that someone new can not understand it. then we could e.g. add an help option that provides this description with the command line (and the GUI could have a tooltip, for other displays)

[ablwr]

This is old.
