    * Are you saying that these must be typed, or are you saying that they can be user-defined? -- K.A.

+     * I am saying that the user should be able to define (e.g. in the config) some set of types/fields/attributes/whatever, following the specification illustrated below, but also be able to use something like `\[[!meta somefield="somevalue"]]` where `somefield` was never defined before. In this case `somefield` will have some default values for the properties described in the spec below. -- G.B.

 
 Each type/attribute/field/whatever (predefined, user-defined, arbitrary) would thus have the following parameters:
 
 * `directive` : the name of the directive that can be used to set the value as a hidden reference; we can discuss whether, for pre- or user-defined types, it being undef means no directive or a default directive matching the attribute name would be defined.
   * I still want there to be able to be enough flexibility in the concept to enable plugins such as `yamlfront`, which sets the data using YAML format, rather than using directives. -- K.A.

+     * The possibility to use a directive does not preclude other ways of defining the field values. IOW, even if the directive `somefield` is defined, the user would still be able to use the syntax `\[[!meta somefield="somevalue"]]`, or any other syntax (such as YAML). -- G.B.

 * `linkdirective` : the name of the directive that can be used for a visible reference; no such directive would be defined by default

+     * yes, with each directory having one page per value. It might not make sense for all fields, of course -- G.B.
+         * (nods) I've been working on something similar with my unreleased `tagger` module. In that, by default, the field-name maps to the closest wiki-page of the same name.  Thus, if one had the field "genre=poetry" on the page fiction/stories/mary/lamb, then that would map to fiction/genre/poetry if fiction/genre existed. --K.A.

+     * as mentioned before, some fields may be made accessible through different template queries, in different form. This is the case already for tags, that also come up in the `categories` query (used by Atom and RSS feeds). -- G.B.
+         * Ah, do you mean that the input value is the same, but the output format is different?  Like the difference between TMPL_VAR NAME="FOO" and TMPL_VAR NAME="raw_FOO"; one is htmlized, and the other is not. -- K.A.

 
 

-Where this approach is limiting is on the kind of data that is passed to (template) queries. 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.
