I used Simile Timeline for the second time on ASP.NET the other day. The Simile Timeline documentation is a bit sparse, but the Google Group supporting it is good.

There's lots of stuff out there on Google about using Simile Timeline with ASP.NET specifically, but as usual much of it is wrong. As a probably pointless attempt to counter those who spend their time copying incorrect data around the internet, here's some correct data about using Simile Timeline on ASP.NET 3.5.

This stuff actually works, and I know because I built it and sold it to someone. If you're in the class of sad copiers, don't forget to correct my spelling mistakes when you steal this.

I was slightly surprised that google didn't turn up a solution to this one right off the bat, but it didn't, so here's my solution. I needed to extract metadata from some images, specifically the stuff which Windows Vista lets you edit from within the explorer - author, title, comments, that sort of thing. A quick check with PS suggests that these fields map variously back to the IPTC (IIM, legacy) and IPTC Core Exif fields; so long as you know which is which you can set the data in either place.

I recall from earlier work that IIS6 doesn'tnecessarily behave the same as IIS7 regarding the way the file system (NTFS) handles and presents extended properties; these days all my stuff is on the newer system so I don't care about IIS6.

There's not much to this, but you need to figure out which fields are which... I did this for the fields I care about in the code below. The file's data is utf-16 coded, which is slightly fiddily to deal with too.

I just shifted a number of sites to this hosting company. As you'll likely be aware it's pushing a sort of virtual host concept which claims to be more flexible than older approaches. It seems to be flexible; it remains to be seen how reliable it all is.

There are a few things which are different here compared with standard IIS7, probably because of their internal architecture.

This site used to live on IX web hosting. I'm not sure what happened at IX, but 2009 hasn't been a good year for them. I ran six web sites there and they seemed to be  more down than up, or at least that's how it felt. My monitoring service suggested that towards the end they were as bad as 80% available on a week-by-week basis. That's bad enough, but even worse were their "customer services"
