I guess I have been living under a rock for several years and never noticed WebDAV. Or maybe I heard about it and thought yet-another-web-standard. WebDAV is Distributed Authoring and Versioning. Techie speak for keeping versions of stuff on a simple web server. Yes, just builds on top of everyday HTTP. It’s everywhere: Microsoft SharePoint, several hundred independent share-ware vendors, and more than a few version control systems use it as a base.
Of course you need something to talk to the server. Click on a document under WebDAV control and down comes the document with a MIME type. If the associated editor is WebDAV-enabled it will take immediately attempt to talk back to the server to see if it is a WebDAV server. Again, Microsoft to the rescue with the entire Office suite and many of your other favorites.
Then some smart guys looked at the V in WebDAV and decided to take a gamble. Presto, a version control system sitting there with almost no work. (Yes, I know there is more to it)
WebDAV should be a favorite of IT staff everywhere: they can toss whatever home-grown CMS that gives them nightmares and just install SharePoint. I think MS is being treated as an enterprise player these days. Maybe.
Lastly are the developer shops with a proprietary product that kinda, sorta does WebDAV things. Maybe they have been living under a rock as well. More likely the idea of ripping apart their product and replacing it with something from Microsoft gives them nightmares.
I think I need to look at job descriptions for other things that should be in my toolkit versus just keyword match on stuff I already know.
