Structured Document Bounding Language

摘要

Using a bounding language to control or restrict the changes that can be made to contents of a structured document (e.g., a document encoded in the Extensible Markup Language, or “XML”), and also includes the bounding language and documents encoded according to the bounding language. A Document Type Definition (“DTD”) is defined as a “bounding DTD”, and one or more structured documents containing editing restrictions are defined according to this DTD. A processing component uses a structured document containing editing restrictions as input, and programmatically determines which fields of another structured document can be edited, which fields should be hidden, and so forth. By restricting the parts of the file that can be edited, users who need to do the editing are shielded from irrelevant details, and can carry out their task with less risk of making errors (and without needing to understand the details of the structured document markup language).

1. A system for controlling editing, comprising:
a computer comprising a processor; and instructions which are executable, using the processor, to implement functions comprising:
determining allowable edits of a plurality of content elements specified in a structured content document by analyzing, using a processing component, content specified in a bounding file, wherein:
a bounding language is defined in a bounding document type definition (“DTD”), the bounding language comprising a plurality of allowable edits that are selectable for applying to the content elements specified in the structured content document;the bounding file adheres to the bounding language defined in the bounding DTD and specifies, in the bounding language, at least one selected one of the selectable edits, and for each selected one of the selectable edits, at least one of the content elements of the structured content document to which that selected one of the selectable edits can be applied;a content language is defined in a content DTD, the content language comprising a plurality of allowable content elements, the content language being distinct from the bounding language and the content DTD being distinct from the bounding DTD;the structured content document adheres to the content language defined in the content DTD and specifies, in the content language, the plurality of the content elements;the structured content document is distinct from the bounding file;the bounding file is not a DTD or schema and does not contain definitional elements of a DTD or schema; anda particular edit of the content elements of the structured content document is allowable only if it is not precluded by the specified selectable edits in the bounding file; andprocessing, by the processing component, a request to edit a selected one of the content elements of the structured content document, comprising allowing the requested edit to be performed on the selected one only if the determining has determined that the requested edit is allowable and otherwise preventing the requested edit from being performed on the selected one.
