Re: [xdi] proposal for binary data literal node

1. Could you have BOTH a binary and a non-binary literal in a context? I.e. have a ! arc and a !! arc.

If not, will the server throw an error if you already have one literal and try to add the other one?

2. In your example, wouldn't the XRI actually be @!1111*logo/!! instead of @!1111*logo!! ?

3. Something is bothering me about the fact that !! is two subsegments. I am worried it will result in ambiguity in one way or the other.

4. I don't understand why you can't load the metadata together with the literal, to figure out whether it is binary or not.

Wasn't this the whole point of what Drummond called "literal contexts"?

XDI TC:

I'm attaching a proposal to represent binary literal values as "!!"

So, for example, the XRI for a my company's logo might be :
@!1111*logo!!

The fact that the image is a binary can't be represented in the metadata, because it is not known which will be loaded first, the literal node, or the metadata about the literal node.

This is a critical issue to optimize persistence of binary objects, which need to be indexed differently.

I'd like to fast track this because we need to store binaries as part of the oxPlus demo :)

Thoughts?
