Linodef is a filter for internal links. It provides tags for internal node and taxonomy term links based on their ID and dynamically embeds node titles, field values and taxonomy term names.

Application field

Those tags are required if you have a text that needs to include references to other nodes/terms or contains elements of other nodes. Some examples:

You write an article that refers to things you've already saved as node or taxonomy term or you want to quote news/other articles (yes, you can dynamically embed whole texts, with or without linking them).
You write a thesis with many difficult terms (the spelling of some of them will change likely) and you require (1) a common spelling as well as (2) links to an explanation for yourself and your readers (each term is a node or taxonomy term).
You write a book and you expect that names of characters will change during the writing process (each character has a node with fields for firstname, nickname, surname etc).

Differences of Linodef in comparison to similar modules

To achieve that goal the ID of a node, ID of a term and optionally a fieldname are the only elements that are saved within your text. The other data is included on-the-fly. That is the difference to similar filter modules that uses node names to create links (wiki-like behavior) or that limit their tags to the Node ID, too, but do not embed anything else. Following is a list of advantages the method Linodef uses has:

if you change the title or field value of the linked node then the title or field value are updated in your text automatically
if you change the name of a term then the name is updated in your text automatically
if the node or term has a path alias then that is used instead of the default /node and /term path (if you change it, it is updated too)
links don't break even if you change the title of a linked node or the name of a linked taxonomy term
the tags are hardcoded and thus reliable so other modules can work with those tags
the filter uses default Drupal hooks solely hence it is easy to maintain i.e. has good chances to stay alive for a long time

Linodef is more than a filter

Now you likely think: "I won't be able to know the IDs of all my nodes and terms." For this very reason Linodef is not limited to the filter tags: Linodef uses hardcoded tags not only to keep simplicity and a common handling but to offer the ability to provide buttons for editors.
