elemental

Elemental is a native XML‑oriented NoSQL database that stores self‑contained documents—XML, JSON, HTML or plain text—in schema‑less collections that can hold millions of items. It offers built‑in validation tools to ensure document correctness while allowing each document to evolve independently. Indexing options support fast structural and full‑text searches, and the engine implements current W3C standards such as XPath, XQuery 3.1, XSLT 3.0, XSL‑FO 2.0 and HTML 5 for querying, transformation and publishing.

The platform includes a web server with document‑oriented APIs (REST, WebDAV, RPC), enabling direct access to stored content, queries and transformations over HTTP. Developers can extend functionality with custom XQuery or Java modules that integrate with the existing API layer, facilitating the creation of web applications or services that manipulate documents on the fly.

Elemental targets developers who need a standards‑compliant, high‑performance store for XML‑centric workloads, especially when combined with search, transformation and web integration directly within the database. It runs on macOS and is positioned as a stable, production‑ready solution.
