After collecting even more grouping examples and performing analysis on those examples, it is quite evident that we need to support ordered, unordered, sparse and non-sparse grouping. There are several options that have been gathered over the past month, listed on the grouping-brainstorming page:
http://microformats.org/wiki/grouping-brainstorming Option #3 seems to have the least number of things working against it. The major argument has been made against Option #3 is that it is a "namespace" approach to ordering. Some have cited the following page for reference: http://microformats.org/wiki/namespaces After pouring over the links on the namespaces page, it seems to be an invalid argument. Namespaces deal with global data markup. Grouping option #3 (and variants) deal with local identification and grouping. These are two completely separate solutions to two completely separate problems. Namespacing is a problem because it requires that all entities marking up data agree on a GLOBAL name space and element names. The proposal put forth in option #3 does not require that any entities agree on a global name space. Element names do not need to be agreed upon either. Option #3 is purely an identification mechanism. I am retracting my support for Option #5 and suggesting that we go with Option #3: http://microformats.org/wiki/grouping-brainstorming#Option_3:_Explicit_class-based_grouping Martin, the hAudio test page that you have up is great. Could we try looking at it using Option #3 as the group markup example? After using the method that you currently have active on your page, I can't help but feel that it isn't quite what we want. There is a reason you had to add CSS to make the tabbing work correctly - you were using XHTML markup methods that shouldn't be used to imply grouping. So, will this work for grouping: - Groups/Collections are identified with the following: hset - Hierarchial ordering is performed by doing: hset.NAME - Ordered grouping is performed by using xoxo Here is an example: hvideo hset.kbv1 hvideo.title = Kill Bill Volume 1 hvideo.collaborator = Quentin Tarantino (role=writer) [hCard] hvideo.collaborator = Uma Thurman (role=writer,role=actress) [hCard] hvideo.collaborator = Lawrence Bender (role=producer) [hCard] ... haudio hset.kbv1.i_walk_like_jayne_mansfield haudio.title = I Walk Like Jayne Mansfield haudio.collaborator = The 5.6.7.8's (role=band) [hCard] haudio hset.kbv1.im_blue haudio.title = I'm Blue haudio.collaborator = The 5.6.7.8's (role=band) [hCard] haudio hset.kbv1.woo_hoo haudio.title = Woo Hoo haudio.collaborator = The 5.6.7.8's (role=band) [hCard] ... himage hset.kbv1.cover_image himage.title = Kill Bill Volume 1 DVD Cover Image (UK Release) -- manu _______________________________________________ microformats-new mailing list microformats-new@microformats.org http://microformats.org/mailman/listinfo/microformats-new
