nuxeo core 2
DESCRIPTION
Content repositories allow you to store simple files, documents with metadata, or even complex documents with structured metadata, and to work with them in various ways. This talk will describe the Nuxeo Core content management engine, and how it builds on standards like JCR 2 and CMIS to provide high-level features to end-users. We will show how Nuxeo Core uses the above standards to provide efficient storage of high volumes of structured or unstructured documents in a flexible manner, using either a JCR or a transparent SQL backend. The architecture and benefits of this new backend will also be presented in an interactive manner.TRANSCRIPT

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
NUXEO DEV DAY 2008
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”
NUXEO DEV DAY 2008
CMIS – Basics
• CRUD
• Hierarchy folders, documents
• Simple properties, lists
• One binary
• Policies
• Versioning
• Relationships
• Queries
NUXEO DEV DAY 2008
CMIS – Advanced
• Multi-filing
• Advanced queries
• Joins
• Full text
NUXEO DEV DAY 2008
Nuxeo Core Storage
• Java API
• EJB remoting
• REST bindings (JAX-RS)
• SOAP bindings (JAX-WS)
• Independent of actual storage backend
NUXEO DEV DAY 2008
Nuxeo Core Storage
• CRUD
• Hierarchy of document
• Complex properties
• Binaries
• Security
• Locking
• Versioning
• Publishing, Proxies
NUXEO DEV DAY 2008
Leveraging CMIS
• Folders, documents
• Properties, lists
• Relationships
• SQL queries
NUXEO DEV DAY 2008
What CMIS lacks
• Complex properties
• Multiple binaries
• Security model
• Only abstract policies are defined
• Proxy model
• Locking
NUXEO DEV DAY 2008
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
NUXEO DEV DAY 2008
Jackrabbit tables

NUXEO DEV DAY 2008
Nuxeo Core 2
• Leverage the Visible SQL Storage backend
• Improved APIs
• Closer to CMIS model
• Versioning, relationships, queries
• Distributed and clusterable
• Faster remote access and caching
• True clusters
• Facilitate cloud-based backends
