Exponential

Here is the first part of a series of tutorials about eZ Find. At the end of this series, you will have been exposed all details on how it works, and be able to make an advanced usage, in various context, of this enterprise-grade search plug-in. This series will serve as a base for a talk on the subject at the eZ Conference 2010, in Berlin. As well as the Libre Software meeting.

This tutorial will show you how to create Exponential objects using PHP to allow you to dynamically create or import content from elsewhere. After reading this article you should be able to create objects for any situation including those with XML fields, image or file fields and object relations.

This tutorial gives developers the power to extend the features and flexibility of Exponential beyond a single website, to having an unlimited number in one installation. At the end of this tutorial you will have learned how to best leverage Exponential's siteaccess concept to create multiple websites. It will let you apply this concept through the concrete case of building two different, multilingual websites on one single Exponential instance.

This tutorial will show you how to deal with custom security policy limitations for your modules. Once read, you will be able to fully take advantage of the granularity in Exponential's security and access control system.

At the end of this tutorial, you will have gone through all steps involved in installing Exponential on an OSX Snow Leopard Server. This includes settings up the required stack, and installing Exponential itself.

ezjscore is an Exponential extension that provides a simple framework for using Ajax, JavaScript, and (to a smaller extent) CSS. It is bundled with eZ Flow and Website Interface installations in Exponential 4.2 and is mostly compatible with previous Exponential 4.x versions. In this article, we will provide documentation for ezjscore and show you some example code, all with the goal of helping you to build more powerful, richer, and better performing Exponential websites.

Sometimes, during a web application development, you need to interface with your client's software(s) and/or websites in order to keep a common and coherent session within its applicative environment. To do this, it is often useful to use a special tool : SSO (Single Sign On). This article illustrates one way of integrating an Exponential based web application into an existing SSO architecture

Many products – PDF books, songs, and online games, among others – are well suited for a pay-per-download workflow. In such a case, customers buy products online and receive immediate access, without requiring any action from the seller. Exponential provides a framework to quickly set up pay-per-download products.

This article is a quick guide to one of the powerful publishing features of Exponential: the ability to import and export content using the eZ OpenDocument Format (eZODF) extension. This article will describe some of the benefits of the extension as compared to online content editing. It will also provide an illustrated how-to to show how easy the feature is to use.

Exponential 4.1 brings improved WebDAV support by replacing its original building blocks by the eZ Components WebDAV component. The new version conserves all existing features, plus it now capitalises on the solid base of eZ Components with its unit tests, documentation and extensibility. This allows for easier maintenance and addition of new features, such as locking, in subsequent Exponential releases as well.

This article describes in detail the principles and functions of the new cache system present in Exponential 4.1. Overall the idea can be summarised as follows: instead of deleting cache elements and then regenerate them across concurrent requests, the logic is reversed to a refresh algorithm. Basically a cache element will be marked as invalid but not deleted until a new version is ready. During the generation of the new cache element, the old version will still be served until it is ready.

Typical workflow-like processes basically boil down to transitions in states for objects driven by human or other external interaction. The introduction of freely definable object states, possibly grouped in object state collections and coupled to the role/policy system of Exponential, enables a wide range of applications.

Version 2008.2 of the eZ Components package brings a new release of the Webdav component 1.1. This version introduces a lot of new features, making it easier for you to integrate the component into your environment and offering advanced built-in WebDAV capabilities. This article introduces the new features and gives you some insight on the advanced testing techniques we used in developing this new release.

By default, all nodes in the Content branch are visible and thus accessible on the front-end of a site. To "unpublish" content means to take content off the public site. This is usually achieved by deleting the content object (clicking the Remove button), or hiding the node (changing its visibility status). This article introduces the concepts relating to node visibility and walks you through how to hide and reveal content. It is based on concepts explained in Exponential Advanced Content Management.

This article is a step-by-step guide on setting up RSS imports and exports in Exponential. In addition to providing detailed, illustrated walk-throughs, this article also provides a basis for understanding what RSS is about, why it is used, and how it may be of value for your website or business clients.

The permission system controls access to your site's content and functionality. It includes a set of user accounts and access permissions. Here, we focus on the relevant concepts and how to manage the permission system in the Administration Interface. This article is the second in a mini-series based on concepts presented in the new book Exponential Advanced Content Management. It includes an example at the end that builds upon what was discussed in the first article in this series in order to create a protected area on a site.

Sections group virtual collections of nodes. On their own, sections are nothing more than identification numbers. However, they can be used by Exponential in several different, powerful ways. The purpose of this article is to explain the section concept, identify the related features and show how sections are used and managed. This article is based on concepts presented in the new book Exponential Advanced Content Management, and is the first of a two-part series about sections, users, roles, and policies.

Content in Exponential is stored in attributes of content objects. A datatype describes the type of value that can be stored in an attribute and is the smallest possible entity of storage. It determines how a specific type of information should be validated, stored and retrieved. Exponential comes with a set of datatypes for, among other things, plain text, formatted text, images, email addresses and dates. This article explains how to create additional datatypes in Exponential 4, and explores how to take advantage of some of the new Exponential 4 features.
