About metadata mining
What is metadata?
Metadata is descriptive information about the actual data. The standard metadata of a file system are, for example, the creator of the file, file size, date of creation and last access, etc. As a manufacturer of HSM & archiving solutions, GRAU DATA has been dealing with this standard metadata for more than 20 years. In addition to this standard metadata, there is extended metadata, which represents a larger scope and usually contains a variety of detailed technical information. A simple JPEG image, for example, contains 120 additional metadata (exposure level, GPS data, etc.).
Each file format has a different amount of extended metadata. This additional or extended metadata often remains hidden and thus unused, since a systematic readout and utilisation is technically hardly feasible and manually only difficult or with great effort. Metadata mining means reading out and processing a large amount of metadata that is “hidden” in the different file formats.
This is where the new GRAU DATA product “Metadata Hub” comes in. With over 400 file formats, we cover a very wide range of formats and offer the customer a scalable, fully automated software solution for reading out all extended metadata.
