Links and series

There are various ways two documents can be related to each other. Some types of links can be formally established in ProFID through series, others cannot.

If several documents share contextual or investigative elements, they are circumstantially linked. ProFID currently does not have a way to formally establish those links.

For example, if two documents of persons arrested in the same car were seized, it is a circumstantial link. In that case, it is recommended that the two documents in ProFID share the same "Operation" field. The operation field is searchable.

In another example, if two persons admitted buying their documents to the same counterfeiter or on the same website, their documents are linked through an investigation. Investigations are not formalized in ProFID, so this type of link cannot be formally established. If you want to mention an existing investigation in ProFID, you can do so in the description of the documents.

A Material link is called a "Series" in ProFID. Series establish formal links between documents in ProFID. A series represents a group of documents that have the same source, based on similar material elements found in all documents of the series. A document can only be part of one series.
