## Turtle Start ##
## Grants Read-Write privileges on <> and <.>.
<>
     <http://www.w3.org/ns/auth/acl#accessTo> <.>, <> ;
     <http://www.w3.org/ns/auth/acl#agent> 
<http://melvincarvalho.com/#me> ;
     <http://www.w3.org/ns/auth/acl#mode> 
<http://www.w3.org/ns/auth/acl#Read>, 
<http://www.w3.org/ns/auth/acl#Write> .

## Turtle End ##

Thus,

## Turtle Start ##
<>
     <http://www.w3.org/ns/auth/acl#accessTo> <.>, <>, <ledger.ttl> ;
     <http://www.w3.org/ns/auth/acl#agent> 
<http://melvincarvalho.com/#me> ;
     <http://www.w3.org/ns/auth/acl#mode> 
<http://www.w3.org/ns/auth/acl#Read>, 
<http://www.w3.org/ns/auth/acl#Write> .

## Turtle End ##

Enables the entity denoted by <http://melvincarvalho.com/#me> to read 
and write data (to and from ) the document denoted by <ledger.ttl>.

You can do that right now.

If you seek uniformity of terms then an accounting oriented ontology 
will do, in regards to the RDF statements that serve as the content of 
the document <ledger.ttl>  :-)
