Semantic Modeling Edge Case List
From GetSemantic
(Redirected from Semantic Modelling Edge Case List)
Following a discussion with earle on #swig, the following is a list of edge cases that one should take into account when producing metadata formats, RDF vocabularies and ontologies, tools and database schemas.
[edit] People
- Not all names follow the Western cultural practice of "Firstname Lastname".
- Gender is not binary: transsexuality/transgenderedness exists.
- Stage names, pen names and pseudonyms exist.
[edit] Books
- Some books are ghost-written.
- There should be some way of linking translations of books together
- A translator is not an author, but has an author-like role.
- Sometimes books are published posthumously.
- Different chapters can be written by different people, and different sections of a book can be translated by different people.
- Different chapters can be written at different times.
- Some book sections denote where they were written.
- Marginalia exists.
- Sometimes books contain pronounciation marks.
- eg. "Self-pronouncing" bibles
- Some books contain the same text in multiple languages (eg. Bibles, ancient philosophical texts)
- Wittgenstein's Philosophical Investigations is published in a parallel English/German edition. earle put up an instance of this in N3.
- There are books which have different editions, but that is due to a translator updating a translation rather than an author changing the text.
[edit] Music
There are plenty of problems with music metadata formats, especially the ID3 format.
- Musical recordings are created by more than one person, or more than one defined group of people. This includes collaborations, mashups, "features", rap battles, remixes, performances and many, many more.
- There can be more than one genre for musical recordings.
