19 \fBjack_property\fR can be used to list, set and delete any and all metadata associated with the ports
20 and clients of a JACK server.
22 There are three main ways to use the command. The \fB-l\fR option is used to list existing metadata. The \fB-s\fR option is used
23 to set metadata. The \fB-d/-D\fR options are used to delete metadata.
25 The \fIidentifier\fR is normally a UUID (UUIDs for ports and clients can be shown with jack_lsp(1)). If the \fB-c\fR option is used, then \fIidentifier\fR will
26 be interpreted as a client name, and its UUID will be looked up internally and used for the relevant metadata operation. If the \fB-p\fR option is used, then \fIidentifier\fR will
27 be interpreted as a port name and its UUID will be looked up internally and used for the relevant metadata operation.
29 The \fIkey\fR is an arbitrary string that identifies the metadata to be operated upon.
31 The \fIvalue\fR is an arbitrary string that defines the value of the metadata to be created.
33 The \fItype\fR is an optional MIME type, given as a string. An empty type for a piece of metadata results in it being interpreted as "text/UTF-8".
37 list all metadata currently defined
40 list all metadata currently defined for \fIidentifier\fR
43 show the value of the metadata associated with key for \fIidentifier\fR
46 deletes all metadata for \fIidentifier\fR
49 deletes the metadata associated with \fIkey\fR for \fIidentifier\fR
52 delete all currently defined metadata
54 -s identifier key value [ type ]
55 sets the metadata associated with \fIkey\fR to \fIvalue\fR for \fIidentifer\fR, with its type set to \fItype\fR if given
58 interpret a given identifier as a client name rather than a UUID
61 interpret a given identifier as a port name rather than a UUID
