Once the data packages have been downloaded from your initial configuration environment and the data has been finalized, you can upload these data packages to your LCS project library. As shown in the following screenshot, the LCS asset library can be used as a repository for the data packages:

The following are the key features of data packages in the LCS asset library:

• Upload new data packages: You can use the + button to create new data packages and upload the data package file.
• Save it in your shared asset library: Similar to the other asset types in LCS, you can save the data package as a shared asset. A shared asset can be imported into other projects within your organization.
• Import: Using the IMPORT option in the Asset library project, you can import the assets shared with you. While importing the assets, you can see all the data project assets that have been shared within your organization or shared by Microsoft. 
• Maintain version: You can use the LCS asset library to manage the different versions of the asset file. You can also view the previous versions and pick a previous version to import it back if needed.
