    Memvid

    Memvid

    Video-based AI memory library. Store millions of text chunks in MP4

    Memvid encodes text chunks as QR codes within MP4 frames to build a portable “video memory” for AI systems. This innovative approach uses standard video containers and offers millisecond-level semantic search across large corpora with dramatically less storage than vector DBs. It's self-contained—no DB needed—and supports features like PDF indexing, chat integration, and cloud dashboards.

    Java library which offers information contained in an OWL resource

    A Java library which reads an OWL resource, e.g. an OWL file, and offers methods to get the contained information. For that is has methods to get all OWL classes together with their subclasses and their data types (i.e. their data properties), all relations of these OWL classes (i.e. all object properties), all OWL individuals together with their classes and their data values (i.e. their positive data property assertions) and all relations of these OWL individuals (i.e. all their positive object property assertions).
