<h2 class="heading settled" data-level="2" id="goods-services-provider"><span class="secno">2. </span><span class="content">GSP</span><a class="self-link" href="#goods-services-provider"></a></h2>
<p>A Solid Goods and/or Services Provider (GSP) is a object in a Solid storage which holds data
about an entity that provides goods and/or services.</p>
<p>A Solid GSP is all built inside a single folder (LDP Container) in a Solid storage.
Let us call the URI of that folder -- less its final '/' -- <code>$ROOT</code>.
It could be say, <em>https://alice.example.org/myBusiness/</em>. Developers must never make assumptions
about where a Solid GSP is stored as users should be able to choose the location they want.</p>
<p>The GSP object is defined in the <code>$ROOT/index</code> document. The RDF type of the GSP is <code>dfc-b:Enterprise</code>.</p>
<div class="example no-marker" id="example-gsp">
<a class="self-link" href="#example-gsp"></a>
<div class="marker">EXAMPLE: A GSP document in turtle</div>
<pre class="include-code highlight"><c- k>@prefix</c-> <c- nn>dfc-b:</c-> <c- g><https://github.com/datafoodconsortium/ontology/releases/latest/download/DFC_BusinessOntology.owl#></c-><c- p>.</c->
<c- g><></c->
<c- b>a</c-> <c- nn>dfc-b</c-><c- p>:</c-><c- f>Enterprise</c-><c- p>;</c->
<c- nn>dfc-b</c-><c- p>:</c-><c- f>name</c-> <c- s>"My enterprise"</c-><c- p>.</c-></pre>
</div>
<p>Other properties can be defined like listed in the GSP shape below (TBD).</p>
<h3 class="heading settled" data-level="2.1" id="enterprise-access-rights"><span class="secno">2.1. </span><span class="content">Access rights</span><a class="self-link" href="#enterprise-access-rights"></a></h3>
<p>By default, the GSP container is private. When one wants to make the GSP public, private properties can still be defined in a separated private document, let’s says <code>$ROOT/index-private</code>, linked with the public <code>$ROOT/index</code> document using the <code>rdfs:seeAlso</code> predicate.</p>
<h3 class="heading settled" data-level="2.2" id="enterprise-discovery"><span class="secno">2.2. </span><span class="content">Discovery</span><a class="self-link" href="#enterprise-discovery"></a></h3>
<p>Type indexes is the recommended mechanism to discover Solid GSP. The RDF class to register an instance of a Solid GSP is <code>dfc-b:Enterprise</code>. Type indexes MUST only register the GSPs owned by the WebId owner. See <a data-link-type="biblio" href="#biblio-type-indexes" title="Type indexes">[type-indexes]</a>.</p>
<h2 class="heading settled" data-level="3" id="products-services"><span class="secno">3. </span><span class="content">Products and services</span><a class="self-link" href="#products-services"></a></h2>
<p>Solid products are defined in <a data-link-type="biblio" href="#biblio-solid-goods-services" title="Solid Goods and Services">[solid-goods-services]</a>.</p>
<p>Supplied products are stored in the <code>$ROOT/supplied-products/</code> container.</p>
<h2 class="heading settled" data-level="4" id="catalogs"><span class="secno">4. </span><span class="content">Catalogs</span><a class="self-link" href="#catalogs"></a></h2>
<p>Supplied products are stored in the <code>$ROOT/catalogs/</code> container.</p>
<h2 class="heading settled" data-level="5" id="third-parties"><span class="secno">5. </span><span class="content">Third parties</span><a class="self-link" href="#third-parties"></a></h2>
<p>Supplied products are stored in the <code>$ROOT/third-parties/</code> container.</p>
<h2 class="heading settled" data-level="6" id="order"><span class="secno">6. </span><span class="content">Orders</span><a class="self-link" href="#order"></a></h2>
<p>Supplied products are stored in the <code>$ROOT/orders/</code> container.</p>

<p>Conformance requirements are expressed
with a combination of descriptive assertions
and RFC 2119 terminology.
The key words “MUST”, “MUST NOT”, “REQUIRED”, “SHALL”, “SHALL NOT”, “SHOULD”, “SHOULD NOT”, “RECOMMENDED”, “MAY”, and “OPTIONAL”
in the normative parts of this document
are to be interpreted as described in RFC 2119.
However, for readability,
these words do not appear in all uppercase letters in this specification. </p>
<p>All of the text of this specification is normative
except sections explicitly marked as non-normative, examples, and notes. <a data-link-type="biblio" href="#biblio-rfc2119" title="Key words for use in RFCs to Indicate Requirement Levels">[RFC2119]</a> </p>
<p>Examples in this specification are introduced with the words “for example”
or are set apart from the normative text
with <code>class="example"</code>,
like this: </p>
<div class="example" id="w3c-example">
<a class="self-link" href="#w3c-example"></a>
<p>This is an example of an informative example. </p>
</div>
<p>Informative notes begin with the word “Note”
and are set apart from the normative text
with <code>class="note"</code>,
like this: </p>
<p class="note" role="note">Note, this is an informative note.</p>
