Example text

This allows an actual resource to be bound with multiple activity regions, but with different names in each of them to avoid confusion. It also provides a simple way for Deep document authors to notate the resources and to place the dynamic content in the document’s HTML content. Fig. 3. Structure of data defined in Deep document files and provenance recorded during reading The runtime component contains the provenance information recorded automatically during Deep document reading. For this information, three activity types are defined in an ebook namespace: ReadingProcess, Activity and EbookExecution.

Total Recall also allows the user to query versions of the relation within a time range, which includes all the modifications that occurred within that range. The syntax of these queries in SQL is as follows: SELECT "column_name" FROM "table_name" AS OF "time" SELECT "column_name" FROM "table_name" VERSIONS BETWEEN "time_1" AND "time_2" Note that querying as of a time in the past is similar to retrieving a state from S(R) given its corresponding transaction time. Consequently, this syntax can be used to reproduce previous results.

6. 2 Deep Document Rollback The other system function driven by provenance is document rollback. During the reading of a Deep document, the user can return to parameter input areas in the document and give different responses. This will trigger new executions and cause the document content to update with different results. Although the resource view allows the inspection of individual results from any execution, the user may prefer to see them in the context of the Deep document content and therefore wish to revisit a previous execution by returning the state of the document to that point in time.
