| Structured & Unstructured Content |
Support for almost all data types, so that applications can use either a fixed or flexible data structure. Provides greater flexibility during the development phase, when target structure has not yet been defined. |
| Alter Data Structures |
When a fixed data structure is chosen, it is still possible to modify the structure afterwards if required (similar to an ALTER TABLE in SQL terminology). |
| Add & Remove Subtypes |
Dynamically add and remove specific data types, also known as mixin-types in JCR terminology, to extend data structures without effecting operation. |
| XML Import & Export |
Export and/or import data in a standard XML structure, as defined in the JSR 170 specification. |
| Advanced Search |
eXo JCR utilizes Apache Lucene, a powerful text search engine library. Lucene provides advanced features such as full text search, highlighting, spell check, fuzzy search, synonym search and similarity search. |
| Versioning |
Enable versioning at any point in the data lifecycle, in order to access history, give labels to different versions, revert to a given version, or compare multiple versions with an extensible comparison framework. |
| XA Transaction Support |
Any updates applied in eXo JCR can be performed in a local or global transaction. If it is necessary to add a JCR Session to a global XA transaction, simply create the global transaction and the JCR Session will then be added as an XA resource. This allows developers to commit and rollback changes directly through the XA transaction. |
| Explicit Locking |
An explicit locking feature prevents concurrent sessions from making modifications on the same set of data. |
| Content Observation |
Option to receive notifications when specific events occur on a subset of data allows custom actions to be triggered as required. |
| FTP / WebDAV Access |
eXo JCR provides two out-of-the-box connectors, FTP and WebDAV + DeltaV. The WebDAV connector relies on a very powerful REST framework that is fully JAX-RS compliant (also known as JSR 311). |
| OpenOffice / Microsoft Office Plugins |
eXo JCR provides plugins that allow users to modify documents directly from OpenOffice and/or Microsoft Office via WebDAV. |
