2.0 Package Capabilities
This package allows you to download Listing information and store it in a variety of file formats (called Targets ). Searches send queries to the MLS in RETS format and returns those listings that satisfy the query. The result set is then translated to the desired file format.
Searches
Listing information is retrieved from defined Sources (RETS Servers) with a form that looks something like this:
Query forms are generated from information supplied when a Source is defined.
Formats
Data is created in a Target defined for one of the following formats .
  • CSV - Comma Seperated Value. This is a rectangular format, or table, that looks loke a spreadsheet. Each cell is separated by a comma. Separate files are generated for data and images

  • OR - Open-Realty 2.0. This format drives a website powered by an Open-Realty pachage.

  • RDB - Relational Database. This option writes separate tables for data and images to a relational database.

  • XML - Extended Markup Language. A single files contains separate XML entities for each listing, including linls to images.
Run Time Control
Controlling run time execution properties is achieved by defining an Extract . Extracts information is used by the GUI to run searches or can be used at the Command Line for use in batch processing configurations. A special Batch Control File is used to support Advanced Query specification.
