A contact is a specialist in an occupation, skill, or area of expertise. Contacts provide your information and perform minor favors, but will expect information or small favors from you in return.
You can describe a contact as being a particular individual, or as a group of similar individuals.
6.4.1 Occupational Contacts
Any occupational keyword can be treated as a source of contacts. However, using an occupational keyword as a source of contacts will always be a stretch. To more reliably draw on particular contacts associated with your occupation, you should take an explicit ability. Use a breakout ability if you are using umbrella keywords.
