Connection tags are used to associate connection data included in an XML file with members. This data can be exchanged with other programs via the ISM link. The connections can also be checked by defined capacities in the XML file.

Connection tags consist of two pieces of data:

1. A Connection Tags XML file, which contains the connection categories, tag names, and member end releases for the connection tag. Connection capacities are also specified for each combination of member and connecting member which may utilize a connection tag. Refer to Connection Tags XML File Schema for additional information on the required structure of this XML file.

2. Assignments of connection tags to members are stored in the STAAD input file. Though this is done within the DEFINE MEMBER ATTRIBUTE command, it is strongly recommended that the user interface features be used to make connection tag assignments as these must utilize only the connection categories and tag names in the associated XML file. Refer to TR.29.2 Connection Tag Member Attribute for additional information on this command.
