Cisco Content Transformation Engine (CTE) 1400 Design Studio is a PC-based application that allows you to provide corporate and Internet content to mobile users by specifying how the existing content should appear when delivered to wireless devices and the Cisco IP phone. When you use Design Studio you do not change existing content; instead, you create transformation instructions that select content and format it for delivery to wireless devices.
The CTE is an appliance-based content-transformation device. The CTE dynamically transforms content according to the transformation instructions created in Design Studio and based on device-specific requirements, such as screen size and markup language. A CTE sits in front of content servers, as shown in the sample configuration in Figure 1-1.
The following sections introduce key concepts and processes that will help you work efficiently with Design Studio:
Before you begin working with Design Studio, it is helpful to understand a few concepts so that you organize your work and create transformation instructions (transformation rules) as efficiently as possible.
To transform a web page containing images, links, tables, and forms for appropriate display on a wireless device, you use transformation operations such as select, clip, move, insert, and modify. Design Studio supports complex transformations through the rules listed in Table 1-1.
Table 1-1 Summary of Transformation Rules
A transformation rule can apply to just one element on one page for one device type. A transformation rule can also apply to many instances of an element across several pages for all device types.
Before you begin applying transformation rules, analyze the web pages you want to transform. Consider whether pages that are based on a common template can be transformed using the same set of rules. Plan how you can achieve a particular transformation with as few rules as possible. Using a small set of rules speeds your initial work and simplifies maintenance.
A project is a container for web pages that you want to transform. Be sure to group in a project the pages that can share transformation rules.
When you save your work in Design Studio, you save a configuration file. A configuration file is what you publish to the CTE.
When a CTE receives a request for a web page, it must match the page to a set of transformation rules, manipulate the page as needed for the requesting device, and then transform the page based on the rules you created in Design Studio.
The CTE recognizes a page based on another type of rule that you create in Design Studio, the Identifier rule. You can identify a page by some or all of its URL, by some unique text on the page, or by a combination of URL and unique text. When you create an Identifier rule, it is important to consider whether any other web page could match the rule.
The "Design Studio Quick Tour" section guides you through a sample Design Studio project, from starting the Design Studio application to publishing your work to a CTE. For each set of web pages that you transform in Design Studio, you will perform the following steps:
1. Create a configuration file in Design Studio.
2. Add a project to contain a related set of web pages that you will transform.
3. Add a web page to a project.
4. Create Identifier rules for the page.
5. Create transformation rules for the page.
6. Publish the page to the CTE you use for testing.
7. Preview the page in an emulator.
8. When a project is ready for production, publish it to a CTE.
