<h2 id="_foreword" class="discrete">Foreword</h2>
<div class="paragraph">
<p>Directive 2007/2/EC of the European Parliament and of the Council [<strong>Directive 2007/2/EC</strong>], adopted on 14 March 2007 aims at establishing an Infrastructure for Spatial Information in the European Community (INSPIRE) for environmental policies, or policies and activities that have an impact on the environment. INSPIRE will make available relevant, harmonised and quality geographic information to support the formulation, implementation, monitoring and evaluation of policies and activities, which have a direct or indirect impact on the environment.</p>
</div>
<div class="paragraph">
<p>INSPIRE is based on the infrastructures for spatial information established and operated by the 27 Member States of the European Union. The Directive addresses 34 spatial data themes needed for environmental applications, with key components specified through technical implementing rules. This makes INSPIRE a unique example of a legislative "regional" approach.</p>
</div>
<div class="paragraph">
<p>To ensure that the spatial data infrastructures of the Member States are compatible and usable in a Community and trans-boundary context, the Directive requires that common Implementing Rules (IR) are adopted in the following areas.</p>
</div>
<div class="ulist">
<ul>
<li>
<p>Metadata;</p>
</li>
<li>
<p>The interoperability and harmonisation of spatial data and services for selected themes (as described in Annexes I, II, III of the Directive);</p>
</li>
<li>
<p>Network Services;</p>
</li>
<li>
<p>Measures on sharing spatial data and services;</p>
</li>
<li>
<p>Co-ordination and monitoring measures.</p>
</li>
</ul>
</div>
<div class="paragraph">
<p>The Implementing Rules are adopted as Commission Decisions or Regulations, and are binding in their entirety.</p>
</div>
<div class="paragraph">
<p>In particular with respect the Network Services, Implementing Rules are required for the following services (Article 11(1) of the Directive):</p>
</div>
<div class="olist loweralpha">
<ol class="loweralpha" type="a">
<li>
<p><em>"discovery services search for spatial data sets and spatial data services on the basis of the content of corresponding metadata, and display the metadata content;</em></p>
</li>
<li>
<p><em>view services as a minimum, display, navigate, zoom in/out, pan, or overlay spatial data sets and display legend information and any relevant content of metadata;</em></p>
</li>
<li>
<p><em>download services enabling copies of complete spatial data sets, or of parts of such sets, to be downloaded;</em></p>
</li>
<li>
<p><em>transformation services enabling spatial data sets to be transformed with a view to achieving interoperability;</em></p>
</li>
<li>
<p><em>invoke spatial data services" enabling data services to be invoked."</em></p>
</li>
</ol>
</div>
<div class="paragraph">
<p>In addition to the Implementing Rules, non-binding Technical Guidance documents describe detailed implementation aspects and relations with existing standards, technologies, and practices. They may need to be revised during the course of implementing the infrastructure to take into account the evolution of technology, new requirements, and cost benefit considerations. Figure 1 illustrates the relationship between the INSPIRE Regulations containing Implementing Rules and their corresponding Technical Guidance documents.</p>

<p><strong>Figure 1: Relationship between INSPIRE Implementing Rules and Technical Guidance</strong></p>
</div>
<div class="paragraph">
<p>Technical Guidance documents define how Member States might implement the Implementing Rules described in a Commission Regulation. Technical Guidance documents may include non-binding technical requirements that must be satisfied if a Member State chooses to conform to the Technical Guidance. Implementing this technical guidance will maximise the interoperability of INSPIRE services.</p>
</div>
<div class="paragraph">
<p>This Technical Guidance concerns the INSPIRE Discovery Services. The Technical Guidance contains detailed technical documentation highlighting the mandatory and the recommended elements related to the implementation of INSPIRE Discovery Services. The technical provisions and the underlying concepts are often illustrated by use case diagrams and accompanied by examples.</p>

<p>INSPIRE Discovery Services allow users and computer programs to search for spatial datasets and services based on their metadata records. This document specifies Technical Guidance for Member States to implement INSPIRE Discovery Services as mandated by the Regulation on INSPIRE Network Services [<strong>INS NS,</strong> Annex II].</p>
</div>
<div class="paragraph">
<p>Following this Technical Guidance will ensure that INSPIRE Discovery Services are implemented in a consistent and compatible way across Europe. It is based on European and International standards, current practices in related stakeholder communities and relevant European initiatives such as e‑Government, and the EU Interoperability Framework.</p>

<div class="paragraph">
<p>This document specifics requirements and recommendations based on the OGC™ Catalogue Services Specification 2.0.2 - ISO Metadata Application Profile for CSW 2.0 [<strong>CSW ISO AP</strong>]. It defines an INSPIRE Profile of [<strong>CSW ISO AP</strong>] to implement the following operations:</p>
</div>
<div class="ulist">
<ul>
<li>
<p><strong>Get Discovery Service Metadata</strong>: Provides all necessary information about the Discovery Service and describes service capabilities;</p>
</li>
<li>
<p><strong>Discover Metadata</strong>: Allows requesting INSPIRE metadata elements of spatial data sets and services from a Discovery Service;</p>
</li>
<li>
<p><strong>Publish Metadata</strong>: Allows editing of INSPIRE metadata elements of resources in the Discovery Service (push or pull metadata mechanisms). Editing meaning insert, update and delete;</p>
</li>
<li>
<p><strong>Link Discovery Service</strong>: Allows the declaration of the availability of a Discovery Service for the discovery of resources through the Member State Discovery Service while maintaining the resource metadata at the owner’s location.</p>
</li>
</ul>
</div>
<div class="paragraph">
<p>In addition, this document defines how a query for metadata should be written, and how to handle multilingual aspects of INSPIRE Discovery Services.</p>
</div>
<div class="paragraph">
<p>This is the initial version of the Technical Guidance document and it has been validated and tested in collaboration with the Initial Operating Capability Task Force. It may be used by the Member States for the initial implementation of the INSPIRE Discovery Services.</p>
