pastwem

Pastwem is a term used primarily in speculative fiction and digital memory theory to describe a framework for capturing, storing, and replaying past events as interactive artifacts within digital environments. In this concept, events are encoded into semi-autonomous memory units called wems, which preserve sensory data, perspectives, and narrative threads from multiple observers. Wems can be accessed, remixed, and replayed under user-controlled permissions, allowing historians, artists, and communities to explore past moments from diverse angles.

The term blends "past" and a neologistic suffix used in online discourse. It is not an established scientific standard but a portable concept used in worldbuilding, theoretical debates about memory, and media archiving.

Key features include standardized data models for multimodal input (text, audio, video, geolocation), provenance tracking, consent governance, and interoperability across platforms. Critics point to concerns about memory bias, manipulation, data sovereignty, and the ethics of resurrecting past experiences. Proponents argue that pastwem offers new avenues for education, cultural preservation, and participatory history.

Examples of use appear in speculative fiction, experimental museums, immersive journalism, and academic discourse on digital memory. In a novel setting, pastwem might allow readers to step into a reconstructed 20th-century marketplace through multiple viewpoints. In education, students could explore a declassified event from the vantage points of participants.
