Album-to-song and tracklists relationships
One more question, please. Is it possible to refer the properties defined at the "sub/child"-pages? I would like to extend the above template/table output with the "Length" column so it could look like a real tracklist. The ?Song property refers to song pages, and every song page has a song definition with the Length property set. It's like the INNER JOIN operation, but I feel like I'm abusing SMW capabilities (and it looks like I'm more of finding a search mechanism like XPath). Is it possible somehow?
In case you go with the #subobject then your data model will most likely be something like:
- An ALBUM is represented by a wikipage ->
- Subobjects are embedded in a page to represent each individual song ->
- Each song has attributes like:
- Song title
- Song index
- Song length
- Song author/composer/writer (optional in case it is a compilation where a song can have different writers from the Album)
- etc.
As demonstrated you attach attributes/properties to an individual song which a #subobject not a page (we are talking about an entity)
If you want to split an ALBUM/SONG by page/subpage then you can take a similar approach only that subobjects need to contain a reference to the album.
For example, looking for an album of song writer YYY where you want to see songs with title and length -> [[Has song writer::YYY]]|?Song title|?Song length.
