Introducing Maver Metadata Format

Maver is a web application that allows you to treat your entire collection of media files as a searchable list and organize your contents without having to re-arrange the raw media files themselves.

At the heart of this powerful capability is Scalp which is a command line utility that allows you to extract the metadata information and generate the thumbnails needed in order to efficiently forward the only necessary data to Maver.

Scalp uses a particular format on the generated files in order for them to be readable by the Maver application. When you execute the following command:

scalp maver:generate

It will generate a series of files inside OUTPUT_FOLDER you had specified in your .env file, for example:


Everytime scalp encounters a media file. It will produce 3 files in return. Wherein the filename is a unique hash representing the contents of that particular file.</a>

  • Metadata File - this is a JSON file which contains the json object with all the metadata associated for that media file
  • Thumbnails - this comes with 3 pre-defined sizes: Small, Medium, Large.
  • files.json - is a simple array that contains the mapping of hash to actual filenames. This is used by scalp to determine which one is already processed so it can skip them.
