I added support for Enclosures to my blog poster today - I can push posts up that specify enclosures, and get those specifications back when I load them from the server. The question I have is this - how do people do this using the common web log APIs? I know that MetaWebLog API specifies the metaWeblog.newMediaObject api - but that only allows for upload, and not necessarily in the context of any particular item. So how do people create enclosure references? I created my own proprietary way of doing it, but I'd like to know what other people do...
