Silva Forum

Silva Forum is an extension for Silva that provides a classic discussion forum environment. It can be integrated with OpenID authentication and a CAPTCHA to prevent ‘spambots’ from attempting to post.

Silva Forum allows site visitors to create topics (subjects or questions) and add comments to existing topics. Entries are ordered chronologically and displayed on multiple pages for extended conversations. Users can preview their posting, and a clickable interface for inserting emoticons in messages is provided.

In a typical setup the public can see and navigate the forum pages. Or, a forum can be configured to be viewable only by authenticated users with Silva’s Access Restrictions. If the forum should be private, a public role can be set as well, limiting access to a select group.

Regardless of whether the forum is open to the public or not, in order to post a visitor must authenticate. Authentication can be with various Zope-based approaches or with OpenID.

Credits

Sponsored by the Bijvoet Center for Bioinformatics, Silva Forum was developed as a collaboration tool for scientists working on the EU-funded project GlycoGold (MRTN-CT2005-05645).

Many thanks to Marc Petitmermet at ETH Zürich for making the OpenID functionality possible.

Silva Math

Silva Math is an extension product for the Silva CMS to enhance Silva Documents with mathematical formulas. Mathematical expressions are edited and stored in TeX format and rendered as PNG images. The formulas are embedded into Silva Documents as Code Sources.

Silva Math uses LaTeX and dvipng to render mathematics. Silva Math benefits from the long tradition of math handling in TeX and LaTeX with its extensive math language and mature rendering capabilities.

An advantage of Silva Math compared to Silva JSMath is mathematical expressions are rendered on the server side as images. Thus, there is no need for JavaScript or mathematical fonts on the client side. This gives the server operator full control over the appearance of the mathematical expressions. On the downside, the printing quality of the expressions is not yet optimal.

Silva Math has been tested with the Silva 1.6 and 2.x series on Linux (Ubuntu 7.10 with TeX Live) and Windows (XP with MikTeX 2.7).

The content types have extra metadata fields for a URL, contact, maker, license info, and version range. Changes can be listed on each release page.

Silva Reference Checker

Silva Reference Checker is an auxiliary product to check references on a site maintained by the CMS Silva.

This product both checks internal references, like included images or relative links to other documents, and external links. It's primary purpose is the internal reference check; the external reference check is currently just an add-on, and may be less useful than other linkcheckers.

The reference checker does only check references; it provides no means to fix broken references.

Silva Z3 View Example

A small Zope3 view example product, which adds a custom view to Silva Documents. Also included in the product is a short readme on how the product works.

Silva Glossary

Silva Glossary is an extension product for the Silva CMS to enhance Silva Documents with glossary functionality. It allows authors to mark up pieces of text and to link these to glossary entries. As a default behavior the glossary description, defined in an external glossary entry object, will pop-up as tooltip when the cursor is positioned over a glossary link. Additionally all glossary entries used in a folder or publication can be displayed on a separate glossary page just like the glossary in a book. Silva Glossary allows for flexible customization of its rendering.

SilvaStatic

SilvaStatic is a Silva extension that allows users to export a static copy of content maintained in Silva to an external website. This allows an organization to run Silva to manage content, but export the content to a simple external web server, for instance at an internet provider. The only thing the web server needs to support is the serving of static files. There also needs to be FTP access so the static files can be copied to the server.

In order to install SilvaStatic, you also need to have either wget or httrack installed, and the ftputil python package (download it from http://ftputil.sschwarzer.net/trac).

We would like to thank Antropia (http://www.antropia.nl) for making SilvaStatic possible.

Silva Ext ETH LDAP

This extension was specifically written to enable LDAP support for ETH's LDAP setup, but it is a good example of how to enable LDAP support in Silva. LDAP can be used to authenticate against and also to get user information such as the email address. It also allows groups defined in LDAP to be used in Silva, together with the Groups product, which must be installed.

Silva Photo Gallery

Silva Photo Gallery is a Silva Product to add photo galleries to your Silva documents. Just add the Code Source to a Silva document and upload your images as "Silva Images" in the same folder as the Silva document (e.g. using .zip files and the full media import feature). Silva Photo Gallery automatically displays the image thumbnails on your page, links them to the hires versions of the photos and adds the necessary javascripts.

Currently it has the following features:

• Open hires version of photo by clicking on it. Loading of the image is done using AJAX technology, so no page reloads are necessary.
• Image title is used as legend. If there is no title the image id is used.
  
• Go to next or previous image using the appropriate links or keyboard shortcuts.
• View the photos as slideshow using the specified time delay.

Silva Photo Gallery uses the Lightbox JS javascript and the enhanced version Slidebox. It furthermore adds resizing of images which are bigger than the current window and automatic slideshow functionality.

Silva Stylesheets

This product provides a Silva Stylesheet asset to the SMI. Stylesheets are editable through the SMI. The styles are split up into Style Sets, which are logical groupings of styles. Each Style Set contains common CSS selectors as found in Silva's frontend.css, as well as a few others selectors.

This product opens up the styling of Silva sites to Authors+, within the SMI. For large companies like universities that have one basic look, and which allow individual departments to customize the look of the content of their site, this is a perfect product.

No longer do site managers need to update stylesheets for the departments.

Silva External Editor

Silva External Editor adds (limited) External Editor support to Silva. With it users can edit objects in the ZMI that would be editable in ordinary Zope folders and Silva's File and Image object types from the Silva Management Interface (SMI).

Silva Conference Extension

Silva Conference Extension provides functionality to let conference attendees register through a Silva site, with a lot of options.  It was specifically built for a customer and his use case (user directory), so it will require a little work to adapt it to other use cases.

Silva MySQL Membership

Use MySQL instead of the Zope user folder for Silva membership management.

Silva Search

Silva Search offers a framework for searching through Silva for documents, and displaying them in nice search results.

Silva Blog

Silva Blog is a blogging tool. It was previously maintained by Guido Wesdorp. Thanks to him for the "blogging" base.

The product is currently kinda basic, but fully functional though. You can add articles and manage them in categories. It's also possible to "enable" the comment feature, but it's not possible to edit the comments yet. I currently disabled them in my blog.

Silva Local Content

This is product containing locale aware content objects based on Silva and Localizer.

With this product You can create content objects in several languages. The different language variants can be edited and published independently of each other.

Silva Display Description

This is an example how a Layout Description could be edited for Silva. The content type is not of any use by itself, but can be used to display other content objects.

The current implementation simply stacks all content objects onto each other. One could think of more complicated examples, like allowing a multi-column layout or the like.

This product also adds example "summary" views for Silva Document. Especially the summary view is somewhat basic, but it should demonstrate how one could define a shorter display suitable for displaying content in a listing.
