Just so everyone is clear, these feeds (the direct ESPN ones) are used by their Bottom Line app, to retrieve information about all games at the same time within the one sport.
There are 11 lineups you can view from the feeds, and it can be viewed in either the original ampersand delimited view (raw), or the xml view, for each feed.
Read through this to see the list:
For those of you using the raw view, I pasted a C#/ASP.Net way to get the feed data into to a dictionary and display it: pastebin.com/ysi76P4p
There are no query string filters, or commands, that I am aware of, for either set of feeds.
Since this was made for an app, to read specific parameters (raw), and eventually specific elements (xml), wysiwyg.
If you are going to aggregate the data / mine it on a continuous basis, I would make sure to save unknown responses / bad responses, if / when they happen.
ex: Overtime comes up as OT, but make sure when it comes to double over time, you can handle it, as it may be 2OT, or DOT, or OT OT. (I knew, but can't remember, sry)
Also, as this is a free way to get decently live scores, I encourage people not to spam it, but cache the results, and only get them when you know the update time will have passed; as you can see in the first parameter / element:
I hope this has helped someone with their interest in these feeds.
If you have information about other feeds, or free services involving the major sports, that you would like to share, I would be more than happy to get to know them.
