Organizations are assigned their own organization codes by energistics. These organization codes typically pop up in the metadata of dlis files, e.g. to identify the producer.
The rp66v1 standard allows vendors to specify their own metadata objects. It also specifies that the type of such vendor-specific objects should always start with the organization code like so:
>>> f.unknowns
dict_keys(['440-FILE', '440-OP-TOOL', '440-CHANNEL'])From he naming we can see that these objects are defined by Schlumberger. The semantic meaning of such objects may only be known to the producer.
