claimTypes:

-----------
|

set-attribute (set a single-valued attribute)
|
||
del-attribute (unsets a single-valued attribute)
|
||
add-attribute (adds a value to a multi-valued attribute (e.g. "tag"))
|
||
unadd-attribute (removes just one value from a multi-valued attribute)
|
||
|
||
Attribute names:
|
||
----------------
|
||
camliContent: a permanode "becoming" something. value is pointer to what it is now.

Old notes from July 2010 doc:
|
||
-----------------------------
|
||
Claim types:
|
||
permanode-become:
|
||
-- implies either:
|
||
1) switching from typeless/lifeless virgin pnode into something (dynamic set, filesystem tree, etc)
|
||
2) changing versions of that base metadata (new filesystem snapshot)
|
||
-- ‘permaNode’ is the thing that is changing
|
||
-- ‘contents’ is the current node that represents what permaNode changes to
|
||
set-membership: add a blobref to a dynamic set
|
||
-- “permaNode” is blobref of the dynamic set
|
||
delete-claim: delete another claim (target is claim to delete)
|
||
-- “contents” is the claim blobref you’re deleting
|
||
{set,add}-attribute:
|
||
-- attach a piece of metadata to something.
|
||
-- use set-attribute for single-valued attributes only: highest dated claim wins (of trusted person) e.g. “title”, “description”
|
||
-- use add-attribute for multi-valued things. e.g. “tag”
|
||
|
||
Tagging something:
|
||
{“claimType”: “add-attribute”, //
|
||
“attribute”: “tag”, // utf-8, should have list of valid attributes names, preferrably not made up by us (open social spec?)
