---++ODS <a>++ links
---+++What are <a>++ links?
The essence of the Web is the *link*. We use it to navigate, discover, form communities, and rank our Web pages on search engines. But each link carries much more behind it than what has generally been exposed.
ODS <a>++ links extend the basic HTML link by including relationships to other data in the ODS dataspace.
---+++Implementation
The implementation (mainly in app.js) is based on [[http://oat.openlinksw.com/][OAT]], the OpenLink AJAX Toolkit, combined with the free-text search features of Virtuoso SPARQL. It is a part of the ODS Framework and other hosted applications may use it.
The main function from the JS file is *generateAPP()*. It takes the following parameters:
* appArea - id of the element containing the area with the links to be <a>++ transformed;
* appOptions - options that will be applied to all links in appArea. They are the same as the options for the anchors from OAT:
* imagePath - path for images used for lookup bubble;
* title - title of the window;
* activation - "hover" or "click";
* width, height - dimensions of the lookup window;
Only links with id attribute are transformed. The default content of the anchor window is:
* Web page - default link location
* Data link (RDF) - RDF representation of the object (if the object is a part of the ODS dataspace)
* Horizontal line
* Found links - list of related IRIs found in the ODS dataspace based on the link text
---+++Usage
Any hosted application may use <a>++ JS by including the script below in the head:
<verbatim>
<script type="text/javascript">
// OAT
var toolkitPath="/ods/oat";
var imagePath="/ods/images/oat/";
var featureList=["ajax2", "ws", "anchor"];
</script>
<script type="text/javascript" src="/ods/oat/loader.js"></script>
<script type="text/javascript" src="/ods/app.js"></script>
<script type="text/javascript">
function myInit() {
OAT.Preferences.imagePath = '/ods/images/oat/';
OAT.Anchor.imagePath = OAT.Preferences.imagePath;
OAT.Anchor.zIndex = 1001;
generateAPP('app_area', {});
}
OAT.MSG.attach(OAT, OAT.MSG.OAT_LOAD, myInit);
</script>
</verbatim>
The following ODS applications support <a>++ links:
* [[OdsBlog][ODS-Weblog]]
* [[OdsBriefcase][ODS-Briefcase]]
* [[OdsAddressbook][ ODS-Addressbook]]
* [[OdsPolls][ ODS-Polls]]
* [[OdsBookmarkManager][ODS-Bookmark-Manager]]
* [[OdsCalendar][ODS-Calendar]]
* [[OdsFeedManager][ODS-Feed-Manager]]
* [[OdsMail][ODS-Mail]].
The settings for <a>++ links can be changed in ODS Framework UI->user name->Edit My Profile->Personal page, drop-down list "Show <a>++ links". The options scope is:
* disabled - this is the default;
* click - the anchor is opened when user clicks the RDF icon shown at the right of the link;
* hover - the anchor is opened when the cursor hovers over the RDF icon shown at the right of the link.
