What do you mean "inline" ? As in "the entries are not compressed" ?

Yes, we use both the offset and size of the window.

* the nodes need properties :-)
* I don't understand the "CopyNode" field in the ER diagram; looking at the
  model, it seems "IsCopyNode" is the problem. That is really "if kind ==
  copynode". IOW, the table just needs "kind"
* why does "String" have a rep ID?
* I'd like to see prop names normalized into another table (there will be a
  lot of duplication there)
* speaking on props, we have some standard props, which we may want to model
  explicitly as columns: created-rev, log msg, author, date
