Because HB.js interacts with a CICS application in this means, a 3270 knowledge stream isn’t generated. No screens are ever scraped, and the resulting integration is extraordinarily sturdy, insensitive to and unaffected by adjustments in the Lead Generation Software CICS application. This method makes it quite simple for any cell, cloud, or internet utility to get CICS knowledge by way of an API or as a callable web service.
They are utilizing an integration solution that leverages the Extended High-Level Language Application Programming Interface . This led them to conclude there was no display-scraping within the mix. However, APIs like HLLAPI or EHLLAPI still scrape information from the 3270 knowledge stream.
If the annotations are embedded within the pages, as Microformat does, this method can be viewed as a special case of DOM parsing. In another case, the annotations, organized into a semantic layer, are saved and managed individually from the online pages, so the scrapers can retrieve information schema and instructions from this layer before scraping the pages. Many websites have massive collections of pages generated dynamically from an underlying structured source like a database.
