80% of the content in an Enterprise is unstructured

Managing & collaborating on files is a painJeff Potts

Where is the latest version?Who changed it last? What did they

change?Which project is this related to?Who should be allowed to see this file?

To make changes?How long do we have to keep this file?Can I get this file in another format?I’m done with this file, what happens

next?

But files are a strange beastJeff Potts

Don’t work well as BLOBs in an RDB– Can’t be indexed– Can’t be streamed– Subject to size limitations

File systems alone aren’t rich enoughNeither are Amazon S3 buckets
