Ordinarily operators of MetaStudio should only define a Data Schema once for a group of Web pages with same semantics. This data schema is defined against a sample page. After definition, the URL of the sample page is recorded into Data Schema Specification File(DSSF) which is stored onto MetaCamp server. If another operator wants to edit this data schema, the MetaStudio downloads the DSSF from the MetaCamp server and retrieves the recorded URL and loads the same sample page into its browser.
