SureDMS Nuxeo Document Object Model

SureDMS uses Nuxeo as its content repository. Nuxeo is a document-oriented platform — it does not expose a hand-written relational schema. Instead, Nuxeo manages its own internal table structure at runtime and exposes documents as typed objects defined by XML schemas (XSD).

From a developer perspective, the persistence model is document-centric:

• Object types are defined as XSD schemas in SC/suredms-nuxeo-extensions/suredms-nuxeo-doctypes/src/main/resources/schemas/
• Java POJOs that mirror these types live in SC/suredms-desktop-client-data/src/main/java/com/sureclinical/suredms/entity/
• Nuxeo server is backed by a PostgreSQL database, but its internal table structure is generated by the Nuxeo runtime — not by application migration scripts
• Nuxeo PostgreSQL connection is configured in SC/suredms-nuxeo-extensions/; default template is postgresql (set via nuxeo.db.type)
