# Named Entity Recognition SDK Licenses

In Named Entity Recognition SDK version 26.3, Named Entity Recognition licenses consist of two files:

- your license key, commonly called `licensekey.dat`, which contains information about the components and operations that you can run.

- the version key, `versionkey.dat`, which contains information about the Named Entity Recognition component versions that you can run.

In general the best way to use these two files together is to concatenate them with a semicolon character (`;`) as a separator.

## Provide License Key Data as a String

In functions where you provide license key data as a string (such as `EdkFactoryCreateWithLicenseKey` and `EdkSetLicenseKey` in the C API), append the license key data with a semicolon character (`;`), followed by the data from your `versionkey.dat` file. Pass this string into the relevant argument of the function.

## Load License Key Data from a File

For functions where Named Entity Recognition loads license key data from a file (such as `EdkEngineCreateFromConfigFile` and `EdkSetLicenseKeyFromFile` in the C API), you can generate a create a valid license key file. Append your provided license key with a semicolon character (`;`) followed by the contents your `versionkey.dat` file. Use the path to this generated file as the license key file path argument of these functions.

## Check License Validity

Each API has a function available to let you check the validity of your Named Entity Recognition license.

- These functions return a JSON object that contains information about your license.

- C API: `EdkGetLicenseInfo`

- Java API: `getLicenseInfo` in the `TextExtractionFactory<T>` and `EDKFactory` classes.

- .NET API: `GetLicenseInfo` in the `EDKFactory` class.

These functions return a JSON object that contains information about your license, such as the status, expiration date, and the versions that the license applies to. The Named Entity Recognition SDK download package includes the JSON schema for this JSON object.
