Silva 2.1a2 Desciption:


Silva is a powerful CMS for organizations that manage multiple or complex websites. Content is stored in clean and futureproof XML, independent of layout and presentation.

Features include versioning, workflow system, integral visual editor, content reuse, sophisticated access control, multi-site management, extensive import/export facilities, fine-grained templating, and hi-res image storage and manipulation. Silva has an open source (BSD) license.

Silva supports a separation between authors who create new content and editors who decide whether content actually gets published. It also allows delegation of editing the responsibilities for a section of a site to others. This avoids a single-person bottleneck without the loss of editorial control.
To assist in the publication process, Silva implements workflow where multiple versions of the same document are stored. A document may be published while a newer version can be edited simultaneously. Silva’s workflow supports email notification to streamline the production process.
Behind the scenes, Silva stores content in XML. This leads to several important advantages: - The same content can be used in different media, such as the web, paper, or word processor content. Web publication of content is native to Silva, but Silva also has export filters to PDF and MS Word, and more can be built when the demand arises.
- The content is future proofed and not out of date as soon as you want to use a new system or present it in a different way.
- The structuring of the content facilitates more sophisticated searching and indexing.
Silva is extensible with new document types and other types of content objects.Features:Authoring - Kupu, a WYSIWYG editor running in Silva, people who work with Word should be comfortable with Kupu. This editor offers a load of new features: - Full Silva integration; Kupu knows about special Silva elements and saves Silva XML transparently.
- Copy and paste HTML from any source (web page, word processor) into Kupu.
- Works in Internet Explorer (5.5 and higher) and Mozilla/Firefox.
- Silva also has a forms based editor for a more structural view of content.
- The editors produce structured XML that is displayed as HTML in a web page, or can be exported using the Docma extension (i.e. as a MS Word document). This also future proofs the information.
- Infinitely nested hierarchy of publications and folders to structure content.
- Metadata per content object. Metadata is extensible; new metadata sets can be added. The metadata can be automatically indexed by the Zope catalog.
- Ability to place dynamic elements in structured documents fetching information from a relational database or by calling a script, using Data Sources.
- All text stored as unicode, which means content in multiple languages can be mixed in single documents freely.
Media - Images and files can be imported either singly or in bulk through importing a zip file. Whole directory structures can be imported creating Silva folders automatically.
- Resize images for web publication. The original high resolution images can still be exported for printing.
- Silva now provides facilities for cropping images. This tool combines with the scaling possibilities to give Authors the means to both scale and resize a high resolution image to web format.
- Extensive abilities to position images in documents.
- Support for Zope's External Editor allows editing files and images through your favorite editor (including MS Office applications).
User interface - Has its own through-the-web user interface with easy access to all features, including access keys. Authors can only access sections relevant to Authors, while Editors and Chief Editors gain more abilities in separate screens.
- User interface internationalized (i18n-ed), so that the user interface can be translated to different languages. In Silva 1.2, there are English, German, French and Dutch versions. Others are in progress.

- Also possible to descend to the Zope user interface for fine-grained control.
Language settings Users can set their preferred language on the user settings page.  Workflow and versioning - Publication workflow: approval by (Chief) Editor is needed in order to publish content. Content can be published as well as expired automatically at a set time.
- Versioning of content. Authors can work on new versions of documents while a previous version remains published.
- Editor can manage publication status of large quantities of documents in one screen.
- Silva can be configured to automatically send email to Authors and Chief Editors for workflow events, informing them about the status of their documents.
- For documents and other versioned content: you can review older versions, compare them, revert the draft version to an older version and remove older versions completely.
- It is possible for site users to subscribe to web pages. They will get an email message sent to them automatically when a new version of the page gets published.
Access management - Separation of responsibilities between Author, Editor and Chief Editor roles.
- Delegation of responsibilities. Editors can approve for publication, Chief Editors can create new (Chief) Editors and Authors. No one-person bottleneck holding up publication.
- LDAP connection is possible using LDAPUserFolder. Search interface for people in LDAP when assigning roles, scaling to large quantities of users.
- Group management (with or without LDAP). Groups can be defined in a LDAP or other data source, but can also be defined locally in Zope, as desired.
- Virtual groups to allow cross-sections between other groups.
- IP Groups allow groups based on IP address, to allow access to selective folders only from an intranet.
- Ability to restrict content viewing access to individual users or groups of users with Viewer, Viewer and Viewer roles.
- Users who do not yet have access to edit objects can optionally be allowed to request this in a user interface.
Documentation - Extensive documentation for Author and Editors, as well as for site Managers, designers and system administrators.
- Documentation can be automatically installed.
Site management - Layout templates; flexible, customizable presentation using Zope Page Templates. Different sub-sites can have different publications and designs.
- Configuration per publication making content available for Authors to add to and edit. It is also possible to completely disable certain content site-wide.
- Ghosts and Ghost folders allow presenting content in a different context than which they are authored in. This allows storing content in a structure paralleling that of the organization for access rights distribution and delegation, but reusing the same content inside topic oriented structures for web publication.
- Virtual hosting support. Areas of the site can be exposed in a separate virtual host for both viewing and authoring.
- Table of contents (TOC) elements can be included in pages to present the local structure of the site.
- Link to manage references to external sites within the table of contents.
- All Silva assets (images and files) can be stored on the file system. This produces substantial performance increases.
- Content caching architecture so that the renderings of individual Silva content objects such as documents can be cached for high-performance display.
XML - Extensive full-media XML import/export system. This exports document content, metadata as well as file and image asset data in a zip file.
- Relax NG schemas describing Silva's content model.

- High-performance, pluggable XSLT rendering architecture to display content such as Silva Document using XSLT transformations.
Silva External Sources (extension) - Enables the flexible inclusion of HTML or tabular data within Silva documents.
- Authors can fill in a form within Kupu or the forms-based editor to parameterize very dynamic scripted content.
- Integration within Silva's content caching architecture.

- Display data from a relational database as a table within a Silva page.
- Upload comma separated value (.csv) data into Silva and dislpay it as a table within a Silva page.
Silva News Network (extension) - Create and manage news and events in Silva.
- News can be aggregated from various areas of the site, reflecting the structure of your organisation.
- Subsites can have their own news displays, while the main page lists all news items.

- Display news pages and/or agenda pages.
- Make news available as RDF/RSS.
- Aggregate news feed from other sites. SNN reads all feed formats.
Docma (extension) - External server that talks to MS Word using COM. This server can be integrated with the Silva server running on another machine (which can run Linux/Unix). Users import and export Word documents using the normal Silva user interface, which delegates the requests to the separate Docma server. If desired the Docma server can also be run standalone on the Windows desktop of end users.
- Export Silva content to a MS Word document. A whole Silva publication consisting of many folders and documents can be exported as a single Word document.
- Import MS Word content into Silva. A single large Word document can be automatically broken up into a structure of Silva folders and documents.
- This allows round-trip editing. Large changes in structure in Word can be reflected into Silva.
