# Standard Grammar – Source

Eduction includes standard grammar files in source form (XML) and their compiled equivalents (ECR). The source files import compiled Eduction standard grammar files and illustrate sample usage. Customers can modify these XML source files and recompile them to customize a grammar for the needs of an Eduction application. The following table lists public entities defined in the XML source files. It excludes the public entities that are republished from the imported Eduction ECR grammar files.

File | Entity | Description
--- | --- | ---
measure.xml | measure/all/eng | An editable collection of patterns that match length, area, volume, and mass.
money.xml1When matching symbols in the money entities, the Eduction option MatchWholeWord must be set to 0 (false). Otherwise, when encountering a string such as $10.70, Eduction will not recognize that $ is the start of a token. Instead, it looks only for matches starting on the 1 and on the 7, and will not return $10.70. | money/all | All currency amounts. NOTE: This grammar file supports some English alphabetic numbers, for example, seven cents, $12 million, one hundred dollars, £5m.

The entities above incorporate the compiled Eduction entities in combination with Eduction XML grammar to create additional entities. The XML illustrates how to use the compiled Eduction entities. You can modify these XML files and compile them into Eduction ECR files that can then be used for specific applications.

The Eduction grammar files have three advantages:

- Allows for fined-grained access to basic entities that include more complex entities. Allows you to customize the complex entities to increase the precision and recall of the matching process.
- Provides both the compiled ECR grammar files as well as source-form XML grammar files that reference them.
- Separate ECR files reduce the memory footprint and file size.
