Nuxeo Core 2JCR, CMIS and the newVisible SQL Storage backend

NUXEO DEV DAY 2008

JCR – Basics

• CRUD

• Hierarchy of nodes

• Simple properties, lists

• Binaries

• Queries

NUXEO DEV DAY 2008

JCR – Unused in Nuxeo

• Versioning – too inflexible

• Locking – too simple

• References – too strict

NUXEO DEV DAY 2008

JCR 2 (JSR-283)

• Compliance levels

• New property types (Decimal, Weak Ref, ...)

• Advanced features

• Versioning, Access control, Observation, Retention & Hold

• Shareable nodes

• Java API for queries

CMIS – Goals

• Simple document model

• Independent of protocol

• SOAP, REST (AtomPub) bindings

• Not tied to a programming language

• Platform, vendor independent

• Basic set of ECM functions

• “Greatest common denominator”

CMIS – Basics

• CRUD

• Hierarchy folders, documents

• Simple properties, lists

• One binary

• Policies

• Versioning

• Relationships

• Queries

Nuxeo Core Storage

• Java API

• EJB remoting

• REST bindings (JAX-RS)

• SOAP bindings (JAX-WS)

NUXEO DEV DAY 2008

What CMIS lacks

• Complex properties

• Multiple binaries

• Security model

• Only abstract policies are defined

• Proxy model

• Locking

What CMIS brings

• Multi-Filed documents

• Can replace proxies

• Unfiled documents

• Record management

• Different versioning model

• Separate PWC, latest/major, version-specific filing

• Standard SQL query model

NUXEO DEV DAY 2008

Visible SQL Storage

• Store data in standard SQL databases

• Use natural mapping of schemas to tables

• Leverage SQL query optimizers

• Facilitate data model migration

• Bulk import/export, backups

• Statistics, external access

• Debugging
