Alfresco Repository Roadmap

 

Vision

 

Overall, Alfresco's objective is to provide the most open, functionally rich, highly scalable and reliable collaboration and content management, via a common repository architecture.

Specifically this means:

 

  • Providing services for collaboration, social networking, and standardized content services for documents, web content, rich media assets and records
  • Being the development platform of choice for building content rich, collaborative applications
  • Scaling to 1 billion objects
  • Utilizing a pluggable, extensible, and embeddable architecture
  • Making it easy to extend and integrate via standards-based and comprehensive Alfresco-provided APIs, providing 100% coverage of all repository services
  • Providing tools for administrators and developers to allow easy application administration and development
  • Ensuring resilience and reliability in mission critical implementations through minimal planned and unplanned downtime
  • Providing integrations with complementary best-of-bread open source components
  • Supporting the relevant industry, technical, and infrastructure standards

Alfresco will invest in the following main areas:

 

Performance

 

Objective: Performance optimization is an on going requirement. Every product change will be implemented with close regard to its performance impact.

Alfresco has been designed from the ground up to provide high performance repository services. As part of this ongoing emphasis on performance, the following areas will be further optimized:

 

  • Node Persistence - Fine tuning of schema and object-relational mappings. 3.1/4.0
  • Eventing (Policies) - Consolidation of events. 4.0
  • Rules - Optimize rule lookup and parallelization (multi-core). 4.0
  • Version Store - Refactoring to improve version creation performance and reduce storage requirements. Available in 3.0
  • Benchmarking - Commitment to distribution of an open source benchmarking framework for both AVM and DM repositories, content objects and application services. Allow our community and customers full ability to test and verify Alfresco repository performance and integrity on their own infrastructure. 3.x & 4.0

Scalability

 

Objective: Alfresco's stated intent is to support a 1 Billion object repository.

In order to achieve this, a number of areas will be address including:

 

  • Indexing - Optimization in both single and multi-node server environments. 3.1
  • Query Engine - Query optimization via query execution plans (see SQL query support below). 4.0
  • AVM Clustering to allow AVM stores to be cluster for both authoring and user-generated content. 3.0 & 3.1
  • Multi-node repository enhancements to optimize multi-server updates and simplify scaling in multi-node repository environment 4.0
  • Benchmarking - Commitment to use the same open-source benchmarking framework as our community and customers may opt to use in measuring and achieving Alfresco performance metrics. 3.x & 4.0
  • Cluster job locking. TBC

Public interfaces

 

Objective: Provide public interfaces and associated documentation for all Alfresco services and protocols.

 

  • Developer APIs for Web Services/REST/JavaScript/Freemarker. Ongoing.
  • Public protocol interfaces for FTP/CIFS/WebDAV/NFS/Sharepoint protocols. Ongoing.
  • Structured Query Language for SQL like query support. 4.0
  • Full repository import/export schema support. 4.0
  • Provide contracts and semantics for all public configuration parameters. 4.x
  • Service Provider Interfaces (SPIs) for repository extension points such as actions, web scripts, and so on. 4.0
    • OSGi support for definition and administration for these extension points
  • Expose additional managed beans via JMX to provide enhanced server management capabilities via third-party applications. 3.1

Services

 

Objective: Expand functional services to offer comprehensive collaboration, social networking, and content services.

Additional services include:

 

  • Rules Definition Services - Allow CRUD support for rules via standardized service. 3.1
  • Permissions and Role Enhancements. 4.0
  • Forms Service - a single forms service which allows for CRUD operations against a variety of Alfresco object types, including DM content models and WCM web forms. 3.1 & 4.0
  • WCM Repository Services - Services for creating, updating and managing all aspects of Alfresco Web Content Management, including Web Projects, sandboxes, AVM structures, Web Form content, static files, permissions, users and groups. 3.1
  • Enhanced native XML support. TBD.
  • Enterprise Search. TBD.

Deployment

 

Objective: Support federated and geographically distributed deployments

 

  • Multi-repository support for search, nodes, workflow, users and groups. 4.0
  • Distributed - content and caching to support access over low-bandwidth/high latency connections, including widely geographically disbursed deployments. 3.1 & 4.0
  • Partitioning - allow for designated servers to take on bandwidth intensive processes (such as media transformations) on behalf of rest of the servers in the federation. 4.0

Administration

 

Objective: Provide GUI-based tools and integrations with third-party management tools to allow comprehensive application administration

 

  • Administration GUI - Including support for administration of users and groups, enterprise authentication, tenants, virtual fileystems, email services, audit, index management, and so on. 3.1 & Ongoing
  • GUI based configuration of model/workflow. 4.0
  • Backup and Restore - full and object level. 4.x
  • Repository health check. 3.1 & Ongoing
  • Remote support/phone home - Support for identifying all installed server components on a system, including modules, patches and specific version numbers.  Support for identifying relevant system environment information.  Support for generating either a static log file (XML format) for email to support, or for generating a feed that can be readily 'published' and access by Support Services. TBD
  • Enhanced JMX support. 3.1

Standards

 

Objective: Provide compliant implementations for the following standards:

 

Infrastructure

 

Objective: Review and update third-party libraries on an ongoing basis and update as appropriate.

Candidates include:

 

  • Spring Security. 4.0
  • Lucence. 3.1
  • AXIS. 4.0

Multi-tenancy

 

  • MT support for Alfresco Share application (3.2)
  • Provide support for AVM store in a MT environment (Share/SiteStore use-case) (3.2)
  • Provide support for LDAP integration (with common LDAP server). TBD.
  • Provide support for multi-server LDAP integration, possibly via chaining/domain support. TBD.
  • Provide support for WCM in a MT environment. Not planned.

Advanced content modeling and referential integrity for web content TBD

 

  • Content Modeling for WCM.
  • Bring concepts from DM world including explicit reference tracking (for referential integrity).
  • Composite objects (relators).
  • Content Model builder administration tools.
  • Align this approach with DM content models so as to allow easy 'flow through' of objects.
  • Provide full referential integrity and validation.
  • Implicit as well as explicit links.
  • Optimized for very quick, publication time check of site content integrity.
