title: An Expressive Model for Comparing Tree-Structured Data creator: Chawathe, S. creator: Garcia-Molina, H. subject: Miscellaneous description: We present a novel alternative to the standard edit-script model used to describe changes in tree-structured data. Instead of a procedural edit script, we use a declarative description of tree transformations. This approach allows us to cleanly describe subtree operations such as moves and copies, leading to simpler differencing algorithms. publisher: Stanford date: 1997 type: Techreport type: NonPeerReviewed format: application/pdf identifier: http://ilpubs.stanford.edu:8090/280/1/1997-65.pdf identifier: Chawathe, S. and Garcia-Molina, H.
