del.icio.usからのリーディング・リスト生成
opmlファイルをマニュアルで作らなくともdel.icio.usを使えばリーディング・リストを比較的簡単に作れるというDanny Ayersのアイデアをもとにしたdel.icio.us Reading Lists。あらかじめdel.icio.us上でrssフィードのurlをブックマークしておき、タグをreadinglistなどとする。del.icio.us Reading Listsで生成されたurlをtaskableやblogbridgeやoptimal OPML browserなどに読み込ませてリーディング・リストを読む。bloglinesでは読み込めない。
Ok, a quick way of collecting a list of resources is to use del.cio.us through its bookmarklet. So I’ll find a few feeds (the feeds, not the blogs) and tag them “readinglist”. I may want to have more than one list, so I’ll add another tag, for example “tech”. Now right away there’s an RSS 1.0 feed available at:
http://del.icio.us/rss/danja/readinglist+tech
In it are item resources, the feeds I’ve chosen. In the RDF world this would be enough, and all the other metadata would be immediately available too. But to engage with the Really Simple world, extra processing is needed to change the format and throw that stuff away. RSS is XML, so XSLT is available. Here’s delicious-to-opml.xsl, 30 or so lines of info-stripping. So, got feedlist in RSS, got transformation, all we need now is a processor. The W3C have one handy.
