Hi folks! Well I have recently had tremendous success in importing extracted data from VieleRETS to Drupal nodes. Thanks to the amazing Node Import module, I was also able to pull the geographical latitude and longitude fields into Location module's fields and images into imagefield module's fields. I'm still learning the nuances of the Node Import modules, so I will be trying to learn how to update existing listings and remove expired listings in an automated fashion. If anyone is interested in sharing some tips or learning how I am doing this, feel free to ask questions. I am also on #drupal on freenode irc (with all the other wonderful drupal heads). At some point, I would like to document the process for others to utilize.

I should also mention that I was rather optimistic about using Feeds or Feed API to import the XML exported by VieleRETS. Having found no way to import images into imagefield fields, I abandoned the effort in favor of using Node Import to pull in the CSV exported from VieleRETS which I had to massage using a custom Perl script.
Hello
Hi webavant,
I'm sticking my toes in the water getting into real estate websites, since a friend asked me if I could help him. Can you get a little most specific about how you are importing RETS?
What I'm envisioning is creating a "property" content type, and importing mls data using node import to the same content type. Is that how it works? Also, how do you update all the imported content to reflect live changes on the MLS?
Thanks!
Sorry for the delayed
Sorry for the delayed response. I was using VieleRETS to export to CSV, then importing to Drupal using the nodeimport module. I have since abandoned my efforts, but I am sure you could easily replicate the system.
Import
Hi tevih -
I use a custom import script that works in three stages.
• Import/update the agent.
• Import/update the agency.
• Import/update the listing and images.
For a site with 20,000+ listings this takes us about 36 hours. Here's a URL to one of the sites that's using this approach: www.mainehomes.com
I hope that helps.
Have Fun - Bill
