isn't this meta data already available in the rules, themselves?

alert tcp $EXTERNAL_NET any -> $HOME_NET $HTTP_PORTS (msg:"ET POLICY Incoming 
Basic Auth Base64 HTTP Password detected unencrypted"; 
flow:established,to_server; content:"Authorization|3a 20|Basic"; nocase; 
http_header; content:!"YW5vbnltb3VzOg=="; within:32; http_header; threshold: 
type both, count 1, seconds 300, track by_src; 
classtype:policy-violation; sid:2006402; rev:9; metadata:created_at 2010_07_30, 
updated_at 2010_07_30;)

so in the above, we have:
- the MSG that states what the rule looks for
- the rule's flow direction, origin and destination
- content that the rule is looking for
- this rule is thresholded looking for one connection from the same source every 
five minutes
- the rule's reference url
- the rule's classification
- the rule's SID and revision
- meta data stating when the rule was created and last updated

other than what might happen to be written up at the given URL, what else are we 
looking for?

so, if this is everything being sought, it is all the available information 
after all, then scanning the rules locally would probably be more of what you 
want to do...
