IT’S ALL ABOUT THE CONNECTIONS…
The definition of a type of connection between two kinds of Information Item Type, e.g. “Ownership” might connect “Person” and “Property” item types. Synonymous with “relationship or association type” in other systems.
A single link between two Items, e,g. Between a Person item with Person_Name = “Fred” and a Vehicle item with California registration “ABC 123 D”.
Sequences and Structures
Connection Types usually connect two different Information Item Types. However, the standard connection types within Metadata Connect are generally between Items of the same type. There are two distinct patterns:
Sequences: These are like lists, but they can include other Sequences, e.g. Workflows are a list of Mechanisms (Applications, Tools and Procedures), but they can also include other Workflows.
Structures: These are used for building hierarchical or network structures, such as organization trees. “Item-Item” and “Org_Structure” can be used this way.
A network of pre-defined connections between related items, represented by Ancestor and Descendant connection types. It may be a simple list - Version 1, Version 2, Version 3 etc., or a more complex structure with many branches (chains) of connected items.
A Metadata Connect query that traverses the links between items, e.g. from an Incident to Evidence to Photos to Suspects. Looking up the ancestors and descendants of an item are forms of navigation.
A Metadata Connect query that finds all of the connecting paths, particularly the shortest path, between two items. This is often useful in establish cause and effect. Person_X cut the brake lines of Vehicle_V, but it was stolen and subsequently crashed into a bus causing injuries to Passenger_Y on board the bus. A Metadata Connect pathfinding query would find that path between Person_X and Person_Y
The history of things that happened to an item, particularly who created/updated or deleted, connected other items to it or disconnected it from other items. It also includes manipulation by other mechanisms, such as computer applications or tools. It is most useful in conjunction with the lineage information in the database.

A term used to describe services or resources that are available over the Internet,rather than using software and hardware on the owners’ premises.
Abbreviation for Comma Separated Value, the file format used to bulk load Items and Connenctions into Metadata Connect.
A mechanism for finding particular items or ranges of items based on a similar detail, e.g. all Documents produced in 2017. A query may also involve connections.
A mechanism for looking for all occurrences of a particular item on the Metadata Connect application, marketing or support websites.
