Is the existence of mongita.errors.InvalidName necessary?

[PlatonB]

mongita.errors.InvalidName: Collection cannot be named 'Nerve_Tibial.v8.egenes_ann_query_res.vcf'.

It seems to me that the prohibition of presence of non-letter symbols in the collection name is superfluous. By the way, MongoDB does not have this restriction.

There are restrictions on names in MongoDB (https://docs.mongodb.com/manual/reference/limits/) but you're right, I believe collections can contain periods in regular Mongo. If I recall correctly, I decided to veer towards more restrictive on the names because it is easy to loosen restrictions and very hard to add them later.

I would lean towards allowing periods if it's something you need to make your package work.

Multiple dots in file names is a common practice in bioinformatics. Renaming back and forth is certainly possible, but it's some extra work. MongoDB doesn't require this, which makes life a little easier:).
