<h2 class="box">What is metadata?</h2>
<span class="fragment">
<p class="box">Metadata is a way of describing data, giving you the information you need to ensure it's fit for purpose.</p>
</span>
<span class="fragment">
<p class="box">It's generally stored using a common format, in a catalog, with persistent identifiers and links back to the source data, so it can be discovered and shared easily.</p>

<p class="fragment"><span class="box-left">Metadata is often viewed as a legislative box-ticking exercise that is hard, costs time and money, and seems to have little direct benefit.<span class="fragment"><small>*cough, INSPIRE, cough*</small></span></span></p>

<p>We've gone beyond creating data and metadata for internal use. Now, data is shared on corporate intranets, on public-facing portals, and in national data catalogs, and efficient use of data is crucial in solving many of today's crises...</p>

<p class="box">Astun have enhanced and expanded our metadata offering to meet these new challenges, and to help you meet emerging best practice guidelines for data management recently issued by the <a href="https://www.gov.uk/government/collections/best-practice-guidance-and-tools-for-geospatial-data-managers" target="_blank">Geospatial Commission</a></p>

<h3>Expanded product</h3>
<p>We use <span class="fragment sentence">GeoNetwork</span>, the leading open source geospatial metadata catalog, as the core of our product. We've now added <span class="fragment sentence">Metadata Crawler</span>, also open source, based on Talend ETL, for bulk metadata creation.</p>
<p>We've also <span class="fragment sentence">expanded the functionality</span> of GeoNetwork, which we'll talk more about shortly</p>

<section data-background-image="./images/overview.png" class="full" data-background-size="contain">
<h2>Overview</h2>
</section>
<section>
<h3>Best Practice</h3>
<p>Geospatial Commission Best Practice Guides state that data should be <span class="fragment sentence">Findable</span>, <span class="fragment sentence">Accessible</span>, <span class="fragment sentence">Interoperable</span>, and <span class="fragment sentence">Reusable</span> (FAIR)</p>
<img style="border:none; box-shadow:none; background:none" src="./images/fair.png" alt="fair principles" with="500"/>
<aside class="notes">Principles emphasise machine-actionability, eg capacity of computational systems to find, access, interoperate, reuse data with minimal human intervention, but can be taken to encompass human interactions with data/metadata as well, we'll use these to talk in more detail about our new offering</aside>
</section>
<section>
<h2>Findable</h2>
<p>Searches start in search engines, not in portals, so we need to make sure our datasets are search-engine-optimised for both good rankings and well-displayed results</p>
<aside class="notes">Metadata and data should be easy to find for both humans and computers. Machine-readable metadata are essential for automatic discovery of datasets and services. Unique persistent ID, rich metadata, searchable and indexable</aside>

<h2>Accessible</h2>
<p>Metadata solutions need to be easy to use, for creators and users, and it should be easy to access the required data</p>
<aside class="notes">Once the user finds the required data, she/he needs to know how can they be accessed, possibly including authentication and authorisation. Standard open protocol, authentication where necessary, accessible even if data is not</aside>

<h2>Interoperable</h2>
<p>Metadata and data need to be in a format that other people or machines can consume</p>
<aside class="notes">The data usually need to be integrated with other data. In addition, the data need to interoperate with applications or workflows for analysis, storage, and processing. Shared accessible language, FAIR vocabularies, qualified references</aside>

<h2>Reusable</h2>
<p>Data should be in formats that can be shared, with quality metadata to ensure it is signed off for publication, used correctly, and is fit for purpose</p>
<aside class="notes">The ultimate goal of FAIR is to optimise the reuse of data. To achieve this, metadata and data should be well-described so that they can be replicated and/or combined in different settings. Accurate, relevant attributes, clear license, detailed provenance, standards</aside>

<section>
<ul>
<li class="fragment bold">We can check that links to View and Download services are working correctly,</li>
<li class="fragment bold">can send automated reminders when datasets are due or overdue an update</li>

<h3>Overdue Reminders</h3>
<img src="./images/overdue.png" alt="overdue reminder"/>

<section>
<p>For our all users, including iShare, we can provide separate public and private catalog endpoints, giving a clear separation between metadata they wish to make publicly available, and that which should be accessible only within their organisation.</p>

<section data-background-image="./images/public_or_private.png" class="full" data-background-size="contain" alt="public or private">
<h3>Public and Private endpoints</h3>

<p>All of this can be deployed quickly and easily on our resilient cloud infrastructure, <span class="fragment sentence">whether you're an iShare customer or not</span>, and <span class="fragment sentence">whether you have existing metadata or not!</span></p>
