Website | Web Slice Format Specification - Version 0.9 |
Web Slices are a web feed technology based on the hAtom Microformat [1] that allows users to subscribe to portions of a web page. [2] [3] [4] [5] Microsoft developed the Web Slice format, and published a specification under their Open Specification Promise. [1] The specification is not published by any independent standards body. Introduced in Internet Explorer 8 Beta 1, Web Slices can be previewed in a fly-out window. [6] As of 2012, [update] Internet Explorer 8 and 9 were the only browsers to support Web Slices natively, although Mozilla Firefox had support via an add-on called webchunks. [7]
A Web Slice has 9 properties: the Web Slice id, entry title, entry content, end time, alternative display source, alternative navigation, alternative update source, and time to live. [1] The 3 required properties are: the Web Slice id, entry title, and entry content.
To disable Web Slices on a web page, add: [8]
<meta name="slice" scheme="IE" content="off"/>
To specify the default web slice on a page with multiple web slices, add: [8]
<link
rel="default-slice"
<!-- Must be "default-slice" -->
type="application/x-hatom"
<!-- Must be "application/x-hatom" -->
href="id of webslice"
<!-- The ID of the web slice -->
/>
<div class="hslice" id = "hslice-id goes here">
<!-- The ID of the hSlice -->
<div style="display:none" class=<"entry-title">Title goes here</div>
<-- The title -->
<span class>="ttl" style="display:none">360</span>
<!-- How often to refresh in minutes -->
<abbr class="endtime" title="10 Jan 2020 00:00:00 UTC"></abbr>
<!-- When the link expires -->
<div class="entry-content">
The content goes here
</div>
While Firefox does not have built in support for web slices, extensions have been created to give the ability to read web slices.
WebChunks is a Mozilla Firefox 3 implementation of Microsoft Webslices. It allows you to "follow" an area of a web page through a dedicated feed bookmarked in a new toolbar. With Greasemonkey, WebChunks can insert webchunks or webslices markup into any web page so the Webchunks extension handles it. [7] [9] [10] [11] [12] [13]
Fireclip is a Firefox addon that lets you "clip out" parts of a website and watch them for changes. It lets you track specific parts of a website in a similar manner to web slices. [14] [15] [16] [17] [18] [19]
Pageslices was another Firefox addon that allowed not only storing parts of websites but also organizing them by adding on custom pages. [20]
Google Chrome, like Firefox, does not have built in support for web slices. However, the extension API new to Chrome 4 allows extensions to be created to give the ability to relatively simply create arbitrary webslices [21] of any content from any page.
Although it was rumored that Opera 10 would have support for web slices, this did not come to pass. [22] [23] Opera does have a "widgetize" feature likened to web slices which allows web pages to be displayed on a user's desktop. [24]
