feature request: add entry based on ISSN number

Hi

Currently we can add books based on ISBN number but it would be nice if we would also add magazines based on ISSN number

https://en.wikipedia.org/wiki/ISSN

How we can have access to that type of magazine information? I saw in ISSN Portal that they have a free tier access to view and retrieve open data about this, but I don't know how we can consume this on JabRef.

A first step could be to extend the DOAJ fetcher https://doaj.org/ in JabRef to extend it with a lookup for ISSN

Otherwise we could try the German library services for magazine lookup:
https://zeitschriftendatenbank.de/services/schnittstellen/json-api
https://zeitschriftendatenbank.de//api/tit.jsonld?q=iss%3D1031-2153

That's nice, I'll take a look and maybe even try to implement it.

What I've found is that we can probably extend the DOAJ fetcher (maybe with a new Class called IssnFetcher or a new method in the DOAJFetcher) because we can use ISSN as a short field name in the search query. In this extension, it has to produce a Lucene Query for GET request. And after the 200 status, it needs to do all the parsing from JSON to our used format.

One thing that I was thinking about is, we are still using the v1 of DOAJ API, and it's already v3, would it be a good idea to update the API version?

[Siedlerchr]

@guipmenezes That sounds great! Feel free to update the api version. The best approach would be to implement the IdBasedFetcher interface.

Edit// Have a look at the ArxivFetcher, we already have interfaces in place and already an identifier class for ISSN;

So it should be possible to implement the methods from the following interfaces:

IdBasedFetcher, IdFetcher<ISSN>
(ISSN needs to extend Identifier as well, that is missing)

[guipmenezes]

@Siedlerchr Sounds good, I'll try it. This IdBasedFetcher interface looks like a better solution, thanks for the advice.

Great! If you have any questions, just ask! Also try to create a (Draft PR) soon, seeing code with context helps in case of questions.
We also have a getting started guide https://devdocs.jabref.org/contributing.html

Hello @Siedlerchr I didn't had time to work on this feature during the week, but now I will give it a boost. I'll create a Draft PR so you can take a look at the code and help me 😁
