[ensembl-dev] Ensembl REST API | Question about Ensembl identifiers

[Thibaut Hourlier]

Hi Ramiro

Ensembl ID and stable id are the same id. We will have a look at how we can rephrase the two documents to try to remove the ambiguity.

The list of entities is correct in the FAQ and https://www.ensembl.org/info/genome/stable_ids/prefixes.html. The document https://www.ensembl.org/info/genome/stable_ids/index.html refers to the stable ids and versioning of genes, transcripts, proteins and exons, this is why they do not have all the entities.

Thanks
Thibaut

Is it just the four entities (gene, transcript, protein and exon) as described here https://www.ensembl.org/info/genome/stable_ids/index.html or are there more entities as hinted here https://www.ensembl.org/Help/Faq?id=488 (e.g., FM, protein family, R, regulatory feature and GT, gene tree)?
