If you aren’t paying attention to your metadata you should be. Workshare, the company that sells the DeltaView product, is sponsoring Metadatarisk.org, the “definitive source for content security.” You’ll find lots of good resources here, from learning about metadata to safe removal of metadata from your documents.
Not surprisingly, this site was introduced along with Workshare’s new metadata removal product. I’m not sure how well this new product works, but I’m all for metadata removal tools. I am still a big fan of Payne Consulting’s Metadata Assistant. Give one of them a try.
