The Lenya Repository API

The Lenya repository API comprises the following interfaces:

Repository

The repository object is the entry point to the Lenya repository. It provides access to the document type registry and allows to create sessions.

Session

A session provides access to the publications and methods for transaction handling. Pending changes are not written to the repository until the session is committed.

Publication

A publication consists of an arbitrary set of areas.

Area

An area consists of a set of content nodes with a site structure associated to them.

Document

A document is a language version of a content item. A document is identified within the area by

• the UUID which is shared by all translations of a document, and
• the language.

Furthermore, documents have the following properties:

• the resource type which specifies the content model of the document,
• the mime type,
• the content length, and
• the last modification date.

The document provides access to its content via the methods getInputStream() and getOutputStream().

Resource Type

The resource type of a document denotes the type of contents which may be stored in its documents. A resource type is identified by a unique name. It may provide a schema, which can be used to validate XML contents upon saving. For more information, refer to the resource types documentation.

Meta Data

For more information, refer to the meta data documentation.

SiteStructure

This interface provides access to the site structure.

SiteNode

The site structure is a tree consisting of site nodes. Each site node has an ID which is unique among its siblings. Thus, a site node can be located using a unique path of the form /sections/news/message003. A site node can reference exactly one UUID, but it is possible to have multiple site nodes point to the same UUID. A site node contains a Link object for each translation. This means that /en/news and /de/nachrichten can point to different translations of the same document.
