ENSURING CONSISTENT METADATA ACROSS COMPUTING DEVICES - A simplified explanation of the abstract

This abstract first appeared for US patent application 18094192 titled 'ENSURING CONSISTENT METADATA ACROSS COMPUTING DEVICES

Simplified Explanation

The patent application describes techniques for ensuring consistent metadata across computing devices. Here are the key points:

  • The user device receives a manifest that includes metadata associated with a file system update.
  • The user device performs the file system update and generates new metadata based on it.
  • A dictionary is created by comparing the metadata records of the original and updated metadata.
  • The dictionary identifies any differences between the two sets of metadata.
  • The user device updates the new metadata to match the original metadata based on the differences indicated by the dictionary.

Potential applications of this technology:

  • Ensuring consistent metadata across multiple user devices.
  • Synchronizing metadata between different versions of a file system.
  • Updating metadata in real-time as changes are made to the file system.

Problems solved by this technology:

  • Inconsistencies in metadata across different devices or versions of a file system.
  • Difficulties in keeping metadata up to date when changes are made to the file system.

Benefits of this technology:

  • Improved data consistency and accuracy across devices.
  • Efficient synchronization of metadata between different versions of a file system.
  • Real-time updating of metadata to reflect changes in the file system.


Original Abstract Submitted

Techniques are disclosed for ensuring consistent metadata across computing devices. In one example, a user device of a plurality of user devices receives a manifest that includes first metadata associated with a file system update of a file system of the user device. The user device generates second metadata of the file system based on performing the file system update. The user device then generates a dictionary based on comparing metadata records of the first metadata with metadata records of the second metadata. The dictionary may indicate a difference between at least one metadata record of the first metadata and at least one metadata record of the second metadata. The user device then updates the second metadata of the file system to match the first metadata based at least in part on the difference indicated by the dictionary.
