For examples, in feeds you'd want all categorization metadata to fall in one place, with some appropriate manipulation (which I still have to implement, by the way), while things like author or title would go to the corresponding feed item properties. Although it all would be possible with appropriate report or template juggling, having such default metadata handled natively looks like a bonus to me. >>> Whereas I prefer being able to control such things with templates, because it gives more flexibility AND control. - K.A. + +>>>> Flexibility and control is good for tuning and power-usage, but sensible defaults are a must for a platform to be usable out of the box without much intervention.

The value of the metadata fields might need some massaging (e.g. compare how tags are passed to tags queries vs cateogires queries). I have problems on picturing an easy way to make this possible user-side (i.e. via templates and not in Perl modules). Suggestions welcome. |
