Description

Improve meta data handling by merging tags, categories, and locations to one table instead of 3 separate tables. Meta data extensions like person would be easier to extend.

comment:1 Changed 7 years ago by sebastian

If all meta data are stored in one table the search syntax need to be adopted as well. The current search allow to have an binary operand for tags, categories, and locations separately (e.g tag1 OR tag2 with location1 AND location2). This behavior must be dropped for sql query performance reasons.

For further reference I name field as some specialized meta data like tag, category or location. E.g "tag:flower" is a field with meta data of a tag and value "flower".

Suggestion: There are required, optional, and excluded fields. Required fields have a plus sign prefix ("+tag:flower" or "tag:+flower"). Excluded fields have a minus prefix ("-tag:flower" or "tag:-flower").

By default all fields are required. So if you query "tag:flower category:vacation location:italy" all fields are required.

If one tag is required marked by plus sign, all other fields are optional. "+tag:flower category:vacation location:italy" means: tag "flower" is required. Media with category "vatation" and location "italy" are optional but ranked higher if available.

"+tag:flower category:vacation -location:italy" means: tag "flower" is required, category "vacation" is optional and location "italy" is excluded.
