<h2><span class="secno">1. </span>Introduction</h2><p><em>This section is non-normative.</em></p>
<p>
The requirements in this document are produced in a high-level, functionally oriented
fashion in order to provide sufficient ground on which to build without going through
the full landscape analysis process given that the APIs being produced concern domains
in which industry experience is already solid.
</p>
<p>
This document is not currently considered to be complete, but rather represents a
snapshot of the DAP WG's thinking at the time of its publication.
</p>
</div>
<div class="section" id="global-requirements">
<h2><span class="secno">2. </span>Global Requirements</h2>
<p>
These requirements apply to all APIs produced by the DAP WG.
</p>
<ul>
<li>APIs <em title="must" class="rfc2119">must</em> be made available in a consistent fashion, hanging off a single access point;</li>
<li>methods that may take a long time to complete <em title="must" class="rfc2119">must</em> support asynchronous, cancellable operation.</li>
</ul>
<p class="issue">
Should the APIs be made available on <code>navigator</code>, <code>navigator.device</code>,
or straight off a <code>window.device</code>?
</p>
</div>
<div class="section" id="application-configuration">
<h2><span class="secno">3. </span>Application Configuration</h2>
<p>
Due to overlapping with Widgets: The widget Interface [<a href="#bib-WIDGETS-APIS" rel="biblioentry" class="bibref">WIDGETS-APIS</a>] and with
Web Storage [<a href="#bib-WEBSTORAGE" rel="biblioentry" class="bibref">WEBSTORAGE</a>], this deliverable has been dropped.
</p>
</div>
<div class="section" id="application-launcher">
<h2><span class="secno">4. </span>Application Launcher</h2>
<p>
The following requirements have been expressed.
</p>
<ul>
<li>
A User Agent <em title="may" class="rfc2119">may</em> provide means for non-web applications to register themselves as handlers for
media types and URI schemes. (Note that this may be outside the scope of this API.)
</li>
<li>It <em title="should" class="rfc2119">should</em> be possible to launch an application for which no media type or protocol handler exists.</li>
<li>It <em title="should" class="rfc2119">should</em> be possible to pass arguments to a launched application.</li>
<li>It <em title="should" class="rfc2119">should</em> be possible to launch an application asynchronously.</li>
<li>It <em title="should" class="rfc2119">should</em> be possible to launch an application synchronously.</li>
<li>For applications that run synchronously, it <em title="should" class="rfc2119">should</em> be possible to catch the output streams (STDOUT/ERR etc.).</li>
</ul>
<p>
The following requirements, while they could be considered to be functionally part of this API,
are already addressed as part of the HTML5 [<a href="#bib-HTML5" rel="biblioentry" class="bibref">HTML5</a>]
<a href="http://www.w3.org/TR/html5/browsers.html#custom-handlers">Custom scheme and content handlers</a>:
</p>
<ul>
<li>This interface <em title="must" class="rfc2119">must</em> enable (web) applications to register themselves as handlers for a specific protocol.</li>
<li>A User Agent <em title="may" class="rfc2119">may</em> provide default handlers for a specific protocol.</li>
<li>This interface <em title="must" class="rfc2119">must</em> enable (web) applications to register themselves as handlers for a specific media type.</li>
<li>A User Agent <em title="may" class="rfc2119">may</em> provide default handlers for a specific media type.</li>

<div class="issue">
<p>
The above suggests support for only VEVENT. However Andrew McMillan makes the following point:
</p>
<blockquote>
"Given that the differences between VEVENT & VTODO are trivial in comparison to the
complexity of their common elements, and that VJOURNAL is entirely a subset of those,
it seems to me there is very little to gain by removing VTODO and VJOURNAL from this specification.
Removal might restrict clients from implementing some potentially useful functionality.
The other supporting components of the specification like VALARM and VTIMEZONE seem to me so essential
in any reasonable implementation of VEVENT that they don't even merit discussion."

<li><em title="should" class="rfc2119">should</em> enable control of the camera's capabilities (e.g. zoom, luminosity, night mode, focus mode).</li>
</ul>
<p class="issue">
Given support for capturing video, we need to take sound capture into account. Once that's supported,
is there any reason not to support capturing sound on its own? If we go there, isn't this a Capture API,
with the ability to list mikes?
</p>
<div class="issue">
<p>
If the user requests a given capture size which isn't available, do we refuse or do we fall back? If the
latter (which is likely) what is the algorithm that is used to find the fallback? It could be (given a request
for 1000x50):
</p><ul>
<li>the camera's preferred default</li>
<li>500x100 (closest number of pixels)</li>
<li>1000x700 (closest longest side)</li>
<li>2000x100 (closest ratio)</li>
</ul>
</div>
<p class="issue">
We could very easily get bogged down in specifying camera capabilities and format feature variants —
how do we decide which ones are reasonably in?

Exposing metadata is tricky, often giving a choice between creating an endless ontology

</p>
<p class="issue">
A lot of this functionality can be provided if the Gallery API is basically a way of
accessing well-known parts of the file system, and if the File System API has a way
of exposing sufficient metadata. This could make for a very simple API.
