The Apereo Open Academic Environment (OAE) project team is pleased to announce the third major release of the Apereo Open Academic Environment; OAE Blue Jay or OAE 3.0.
OAE Blue Jay introduces a new and improved Document Previewer that allows rich documents such as PDFs, Microsoft Word and Excel files to be displayed and embedded directly within OAE without requiring a download. OAE Blue Jay also supports migrating all existing documents to this enhanced version. A screencast of the improved Document Previewer in action can be found at http://oaeproject.org/node/46. In addition to this, OAE Blue Jay also brings a wide range of usability improvements based on usability testing. Document Previewer High-fidelity previews Prior to OAE Blue Jay, the Document Previewer converted the pages inside of a rich documents to images. While it produced picture-perfect previews, it had some drawbacks: Generating image-based previews takes significantly longer Image-based previews are large in file-size, degrading the document browsing experience Image-based previews degrade in quality as zoom level increases Image-based previews are inaccessible to screen readers In the OAE Blue Jay release, we have replaced the image-based processor with the pdf2htmlEX Open Source project, generating high-fidelity HTML for each of the pages. This enhances previews in the following ways: Generating previews on large documents is orders of magnitude faster Documents that are mostly text are significantly smaller in file-size Zooming of text can be achieved natively in the browser without loss of preview quality Accessibility improvements as the text is available in the HTML Easy to use viewer These new HTML-based previews are displayed in OAE inside of our new simplified Document Previewer. This allows you to easily flip through pages, request a specific page or zoom in and out of pages. On top of that, this new Document Previewer is also fully internationalizable and skinnable. Full screen reading It is now possible to enjoy reading documents without distraction by using the full-screen mode feature available in the new Document Previewer. Solid foundation This new Document Previewer is only a first step. It opens up the door to indexing and searching the full text of these documents, as well as allowing for annotations to be made inside of documents.
