IMF FAQ

by Mr. MXF

I get asked a lot of IMF questions. Many of them are not confidential and many of them are repeated over and over again, so here's a selection of them to help you wander the IMF information forest in relative safety.
Q == question. A == short answer. R == references info. E == example

• Q#1886 - What is the maximum filename length in IMF?
  • A: IMF does not use filenames so there is no upper limit
  • R: ST 2067-2 does not mention filenames. ST 2067-2 IMF Core Constraints references ST 429-9 Asset Map. In ST 429-9 clause 7.1 defines an Asset's Path as a URI defined by RFC 3986. A URI that has global scope should not exceed 255 characters. Filenames are definitely not global scope and are therefore unconstrained by any standard.
  • E: local scope: cpl-c7f5e0cd-52e1-42f2-8d5b-cd6607f678b4-DERIVED-FROM-a8dbb61c-d2ee-4b34-9188-5cbffcb6c0c6-DERIVED-FROM-15bd6a26-d8cf-4625-83de-451f91d9023b -DERIVED-FROM-4c293f11-13d2-4252-92a1-9dc729c46f68.xml is a valid filename but may break some QC tools.
  • E: global scope: https://s3.eu-west-2.amazonaws.com/mrmxf-public/www/samples/plan-text-sample.txt is 90 chars
