I want to create a database linking different web pages together. Each such link should be able to carry one or several comments to.
I want to be able to search it by URLs, titles and comments.
There should be an API so I could use this from different software (like Wordpress etc).
The software I am looking for to do this should be open source and run on a web server (maybe my own server). I expect it to use MySQL and a common programming language.
Is there any such software available?
