Hi, We've been running into a somewhat logistical problem of having too many bag files, and no good way to organize them. Has anyone given thought to the idea of adding meta-data to the .bag files? It would be useful if we can attach a description and keywords so we can quickly find relevant bags. For example, you would keep all your bags in a specific directory, and have a ros tool that is able to search through them based on keywords, topics, or message types. Since adding explicit meta-data to the bag format might cause compatibility problems with current bag tools, perhaps a round-about solution would be to attach a "metadata" topic to each bag.
