> The "tag" of the data doesn't actually tell you the type of the data by itself (most of the time at least), so while you can say "there is something of length 10 here", you can't say if it's an integer or a string or an array. Could you explain what you mean? The tag does indeed encode this: for an integer you'd see `INTEGER`, for a string you're see `UTF8String` or similar, for an array you'd see `SEQUENCE OF`, etc. You can verify this for yourself by using a schemaless decoder like Google's der-ascii[1]. For example, here's a decoded certificate[2] -- you get fields and types, you just don't get the semantics (e.g. "this number is a public key") associated with them because there's no schema.

No, far from "inventing ASN.1 again", TJSON could potentially be a very useful format for representing equivalent structures to ASN.1, similar to: https://github.com/google/der-ascii
