Why not? :) I (Thiago) for a long time had an idea of writing a blog engine that was heavily based on tags and which provided specific the option of having per-tag and per-post style. In addition, it would be used as a light CMS too, so that's why Eloquentia uses the word 'page', not 'post'.
Another reason was creating a pratical, useful project to learn some new interesting stuff like Apache Tapestry 5.4 (due to the project at work, I barely had used T5.2 and later), MongoDB (I've never used a NoSQL database before) and Twitter Bootstrap.
Each tag has:
- A name, which can only use lowercase letters, digits or dashes ('-')
- A boolean 'subdomain' field which defines affects the tag URL.
- A title
- An optional subtitle, which is used in the tag page and in pages which have this tag as their first one.
- CSS which will be added to its page and to all pages which have that tag.
The URL of a tag is based on its the name. For example, if a tag name is tapestry, the URL
will be tapestry.domain.com if it's marked as a subdomain and domain.com/tag/tapestry otherwise.
Each page has:
- An URI, which is used to define the page's URL. It can use lowercase letters, digits, dashes ('-') and slashes ('-'), but cannot start or end with a slash.
- A title
- A teaser, which is a short text describing the page and used in the page listing and RSS feed.
- The content itself.
- The date (including time) in which it was posted. Dates in the future are used to schedule when a given page should appear.
- The date (including time) in which it was last edited
- An author
The URL of a given page depends on its first (as in order) of its tags, if any. Suppose a page with
URI stuff/eloquentia and tags project and java. If project is a tag marked as a subdomain, the URL
of the page will be http://project.domain.com/stuff/eloquentia. Otherwise, it'll be
http://domain.com/stuff/eloquentia.
Eloquentia is configured to use a local MongoDB instance without authentication. Its page, tag and user
collections are supposed to be in the eloquentia database. This isn't configurable yet.
