Abstract

Disclosed is an example for hosted applications to provide its mobile clients the ability to reduce mobile-server chattiness for transfer of rich text with images embedded and provide in-context offline viewing. The application may be hosted on a common application server and by using this, the application server settings do not need to be altered, thus allowing some applications to reduce the calls vs other application which chose to do otherwise.

At least one non-text object (such as an image or picture) has been suppressed.

To convert referenced images present in rich text data into a self contained blob of rich text which enables incontext images to be viewed on mobile devices in offline mode

Rich text data is comprised of text, images, links etc. Following the linked data model and REST format, in many quality management solutions which follow linked data model, the images are a stored as a separate resource in the repository.

Normally the web/mobile clients do asynchronous call to get the rich text data followed by another series of asynchronous calls to get the image content. This will reduce the number of calls made to get complete rich text data to single asynchronous call without altering the application server settings. For offline viewing, if the data is downloaded with different async calls, the data (images & text) loose context, this example avoids that and allows data to be visible in offline mode maintaining the context of images.

In brief, an asynchronous call made by the mobile client to get the rich text data, server replaces the linked images with browser readable blob format (Data URI format). It then sends the rich text containing image blob to mobile device and it is then stored on a local file on the mobile device. In the offline mode, read the rich text data from the file and show it in the browser.

Advantages:
1. Even if there are many images in the resource, calls made to get complete rich text data is reduced to 1.

2. This mechanism does not require the application server settings to be changed ie. there could be multiple applications running on application server and some applications may allow data to be clubbed together while others will not.

3. In asynchronous data GET, once the data is received on the mobile application and saved for offline viewing, the data & images cannot be remapped to exact locations without computation intensive parsing, this can be avoided with this approach.

4. Rich text data & images can be seen in offline mode (without loosing the context)

5. The application will not need multiple service...
