The Entry Selection Language

The Entry Selection Language (ESL) is used for selecting entries in a Maestro project based on the properties of those entries. ESL expressions can be of arbitrary complexity and can use parentheses and logical operators. A typical application for the ESL would be for filtering. An ESL expression can be used to select only those entries that meet a particular criterion, usually based on entry properties. Once selected, those entries can be displayed in the Workspace or exported to an external file.

While the ESL is similar in appearance to the Atom Specification Language (ASL), they are used for quite different purposes - the ASL for specifying sets of atoms in the Workspace, the ESL for selecting entries in the project.

The syntax and use of Maestro's Entry Specification Language (ESL) is described in the topics listed below.
