Metadata

Metadata is a list of names with corresponding values. The Metadata is attached to an objects animation point. When using any of the DspAnGetMetadata Cicode functions this Metadata is processed, with the field values retrieved, and set at runtime. At runtime Metadata cannot be added or removed.

Metadata can be implemented when configuring the following animation objects-Free Hand Line,Straight Line, Rectangle, Ellipse, Polygon, Pipe, Text, Number, Button, Symbol Set,Trend, Paste Symbol, Active X, Process Analyst (Database Exchange Control, Pelco Camera View Controller, CitectSCADA Web Gate Control)

Note: Metadata can also be assigned to super genie associations. See Passing animation point metadata as Super Genie associations for more information.

To add a Metadata entry:

Click Add or double click on the row to make it editable.

Insert the Name of the metadata.

• To start with an alphanumeric or “_” character
• To contain only those characters that are allowed in variable tag names (excluding the period character ‘.’), and not contain any white space.
• Be no more than 253 characters in length
• To be unique across a specific animation point.
• The name cannot be changed at Runtime.
• The name can contain Genie substitutions

Insert the corresponding Value of the specific metadata entry.

• The Value can contain Genie substitutions. E.g. %Level%
• To contain only those characters that are allowed in variable tag names (excluding the period character ‘.’), and not contain any white space.
• To be no more than 255 characters in length.
• Literal strings are supported and be specified within single quotes e.g.'Literal'.

Note: At runtime Values can be changed, however when the graphics page is closed the Values will revert to the original configuration.
