This is the collaboration content management platform in Alfresco. It is built on the Surf framework. The Surf framework was developed by Alfresco, but in 2009 Alfresco began working with Spring Source and announced the Spring Surf Extension framework. Later on, both Spring Source and Alfresco were collectively developed and are available as plugins in Spring MVC 3.x.

Alfresco Share simplifies document capturing and sharing, and the retrieval of data for teams, resulting in better collaboration. This in turn increases the productivity of teams and reduces the volume of e-mails.

Alfresco Share also provides advanced administrative tools. It supports module-based extension, which supports the ability to remove, add, or modify any component without changing any out-of-the box code.

This is the main core of Alfresco. Alfresco repository is a bundle of service implementations based on the open standards of CMIS and JCR. This service provides cutting edge content management features such as:

These services provide a public interface based on REST/CMIS or Java JSR-170 protocol standards which allows the client application to communicate with the repository. Alfresco Share communicates with the repository using the REST interface.

The content repository is more than a normal database application, due to the level of control over individual content it provides. Access to content is wrapped by a security layer which prevents any unauthorized access. The fine-grained security control requires a more complex approach than a traditional database application.

In Alfresco, the actual binary stream of content is located in the file system. The file folder structure and reference to this binary stream is maintained in the database.

Access to content stored in a repository is very important for any ECM. Alfresco supports various protocols, such as CIFS (Common Internet File System), WebDAV, and FTP.

These protocols allow you to support the mapping of the same file folder structure as the repository to a virtual filesystem. With these protocols, any tool that can read and write a filesystem can read and write to an Alfresco repository. Users can still use Alfresco as a locally mapped network filesystem. CIFS provides advanced compatibility with the mapped operation system. With the CIFS protocol, Windows users can use the Windows offline synchronization feature with an Alfresco repository. These virtual filesystem protocols allow users to edit and view content using their locally installed tools.

The database holds all the content related information, such as metadata, content association, content binary stream location reference, and folder structure. The database also stores information related to users, workflow tasks, audits, and so on.

Alfresco supports various database vendors, such as MySQL, PostgreSQL, Oracle, and so on. Oracle is only supported in Alfresco Enterprise Edition. Database schema and more information will be covered in Chapter 8, The Basics of the Alfresco Content Store.

The content store is a term used for the filesystem location where the actual binary stream of content is stored. In Alfresco, only the reference to the content is stored in the database. The actual content is stored in a filesystem. This filesystem can be any normal NAS or SAN mounted drive. This architecture allows Alfresco storage to grow exponentially and makes Alfresco scalable.

Searching is a very important aspect of any ECM system. Alfresco supports searches using Apache Solr. All content, metadata, and permissions associated with content in Alfresco are indexed in Solr, which allows fast searches and access to content stored in a repository.

Solr can be bundled with Alfresco on the same machine, or it can be installed as a separate tier. This design allows the horizontal scalability of the search tier. Alfresco and Solr communicate with each other asynchronously.

Alfresco can be used as a document management solution for any organization where the documents are business critical, and storing and retrieving them effectively is very important for the business. For example, contracts are very important documents for many firms. All contracts can be stored in a central location within Alfresco. Strong access control can be applied to each contract document, so only authorized users can view/edit the contract.

Metadata information from the contract document can be extracted and indexed in Alfresco, which allows users to search any contract easily. As Alfresco supports full-text searches, users can search the contract document based on its content. The versioning features of Alfresco can be leveraged to ensure that all the versions of the contract are kept.

Alfresco provides a strong audit trail, so all the actions taken on the contract by any user can be captured and an audit report can be generated from them very easily.

Alfresco also supports integration with various scanning and OCR solutions, such as Ephesoft, so any paper contracts can be scanned, classified, and stored in the repository.

For contracts, the review and approval process is very important. Alfresco has strong business process management which can be leveraged to automate this process, reduce the length of the approval cycle, and improve efficiency. As Alfresco can be accessed from the Web, users can view documents and perform operations from any location.

Alfresco record management is a great solution for any organization where compliance is important. It is simple and very user-friendly. Users can adopt this system easily.

It can be extended to create a single centralized repository to manage all kinds of electronic records. Alfresco provides strong access control, so all records are secure. The policies for record use, storage, and disposal can be easily defined with Alfresco record management.

Alfresco record management is designed based on United States Department of Defence 5015.2 record management standards.

With Alfresco, you can easily drag and drop records into the system. Business rules can be defined to classify and mark them as records. A disposition policy can be defined and automated, which includes the transfer of records or their complete destruction after a given period. In addition to this, there is strong auditing that captures all actions on the records.

Alfresco provides different reports that show recent records, records due for expiry, records due for destruction, and records due for transfer.

Alfresco can be used in collaboration solutions within an organization, along with content management. For example, a marketing team can work on different projects. Alfresco Share can be used as a collaboration platform. Each marketing project can be created as a different space. Only members of that project can have access to that space.

Teams can upload, share, and discuss content within this space. There are dashboards which can be configured as per user needs to see the activity in the project and notifications. Alfresco acts as a central repository to manage all types of marketing documents.

Alfresco provides a feature for publishing content to any social platform, including Twitter, SlideShare, and Facebook, which can be leveraged and content can be published directly.

With Alfresco, content can be shared with external users in a secure and controlled way.
