Re: Using a DID Identifier in a filename?

How about these additions to #didlang (version 0.4)...

+did:color ...to register a new DID Method name

+did:color:mygray Name="My Gray" A=255 R=10 G=10 B=10 ...to add a new DID Chain: a new DID Identifier and associated DID Agent Cluster and subsequent DID Object

-did:color:mygray ...to deactivate the DID Chain associated with the DID Identifier

"More news at 11...",

As an aside: it would be interested to fuse did-cli and #didlang: https://youtu.be/mf0aKLvJoCw

Great question, Michael.

I've also been faced with this problem (storing did documents & keys for the did-cli tool), and I've found that URL-encoding the DIDs turns them into file system friendly identifiers.
I like Orie's suggestion too, though.

I like the latter Orie. It's also a good way to avoid file system directory size related performance issues. Thk you

Yes, I have had this problem before.

and yes, you can just convert all reserved characters from the ABNF.

https://www.w3.org/TR/did-core/#did-syntax (beware of "." and "_", etc)

If you can get away with dropping the "did:method" part, your files will be more readable.

You can also consider a folder structure approach: /did/method/id.json

Given that a colon is an invalid filename character (at least on most PCs), does any one have any thoughts about a convention for mapping a DID Identifier into a filename?

For example, using a simple mapping of a colon into a dot (period)?
