      <description>&lt;p&gt;Interoperability is a central aspect of the SmartOcean platform which provided data provision and consumption via standardised REST and MQTT cloud APIs, and data and meta-data formats for service integration.&lt;/p&gt;&#xA;&lt;p&gt;Work is ongoing on standardising a data- and meta-data format for the SmartOcean platform to be used both internally in the platform and for exposing data. The figure below shows the current basic data model being used by the SmartOcean platform.&lt;/p&gt;</description>

      <description>&lt;p&gt;Data providers are systems and applications that actively deliver marine data-sets and data streams to the Smart Ocean platform.&lt;/p&gt;&#xA;&lt;p&gt;Data is currently being provided to the platform from the &lt;a href=&#34;https://www.hi.no/en/hi/laboratories/austevoll-research-station&#34; target=&#34;_blank&#34; rel=&#34;noopener&#34;&gt;Austevoll Research Station&lt;/a&gt; of the &lt;a href=&#34;https://www.hi.no/hi/en&#34; target=&#34;_blank&#34; rel=&#34;noopener&#34;&gt;Institute of Marine Research&lt;/a&gt; where the SmartOcean Pilot Demonstrator 1 has been deployed.&lt;/p&gt;&#xA;&lt;p&gt;The pilot demonstrator encompass underwater sensor hubs and nodes with underwater wireless communication from&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&lt;a href=&#34;https://www.aanderaa.com/profiling-current-meter&#34; target=&#34;_blank&#34; rel=&#34;noopener&#34;&gt;Aanderaa Data Instruments&lt;/a&gt; (AADI/Xylem)&lt;/li&gt;&#xA;&lt;li&gt;&lt;a href=&#34;https://wsense.it&#34; target=&#34;_blank&#34; rel=&#34;noopener&#34;&gt;W-sense&lt;/a&gt;&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;Data is being provided to the platform via the ingestion messaging service. The data ingestion service does not provided any constraints on the format in which data is being provided in order to support integration of a wide range of data sources.&lt;/p&gt;</description>

      <guid>https://smartoceanplatform.github.io/page/consumers/</guid>
      <description>&lt;p&gt;Data streams from the SmartOcean platform can be consumed via the:&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;The REST API of the data space service&lt;/li&gt;&#xA;&lt;li&gt;The MQTT core messaging service&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;ThingSpeak channels consumes the some example streams on the platform and has been setup for demonstration purposes:&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;&lt;a href=&#34;https://thingspeak.com/channels/2129424&#34; target=&#34;_blank&#34; rel=&#34;noopener&#34;&gt;Virtual Sensor Hub ThingSpeak Channel&lt;/a&gt;&lt;/li&gt;&#xA;&lt;li&gt;&lt;a href=&#34;https://thingspeak.com/channels/2161887&#34; target=&#34;_blank&#34; rel=&#34;noopener&#34;&gt;AADI Austevoll Demonstrator - South Node&lt;/a&gt;&lt;/li&gt;&#xA;&lt;li&gt;[AADI Austevoll Demonstrator - North Node](sensor node under maintainance)&lt;/li&gt;&#xA;&lt;li&gt;&lt;a href=&#34;https://thingspeak.com/channels/2161890&#34; target=&#34;_blank&#34; rel=&#34;noopener&#34;&gt;W-sense sensor node 1 and sensor node 2&lt;/a&gt;&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;Data streams from the platform are also being consumed by and made available via the &lt;a href=&#34;https://www.nmdc.no/nmdc&#34; target=&#34;_blank&#34; rel=&#34;noopener&#34;&gt;Norwegian Marine Data Centre&lt;/a&gt; and via the Norce Enlighten Portal.&lt;/p&gt;</description>

      <title>Data space service for historical time series data</title>
      <link>https://smartoceanplatform.github.io/page/dataspace/</link>
      <pubDate>Fri, 19 Dec 2025 00:00:00 +0000</pubDate>

      <description>&lt;p&gt;The SmartOcean data space service provides uniform access to platform data services and external data sources. The data streams of the core messaging service are forwarded into time series collections for longer-term storage&lt;/p&gt;&#xA;&lt;p&gt;The data space service which currently uses the MongoDB cloud-based storage and provides an internal provider REST API for storing data and an external data consumer API for retrieving data. As the data service evolves, it will also be able to serve as a proxy service for access to external data services.&lt;/p&gt;</description>

      <title>Edge integration of sensor networks</title>
      <link>https://smartoceanplatform.github.io/page/edge/</link>
      <pubDate>Fri, 19 Dec 2025 00:00:00 +0000</pubDate>
      <guid>https://smartoceanplatform.github.io/page/edge/</guid>
      <description>&lt;p&gt;The primary purpose of the edge integration service is to support the delivery of data from the underwater wireless sensor networks (UWSNs) into the data services of the platform.&lt;/p&gt;&#xA;&lt;p&gt;The edge integration facilitates the transfer of data from the information acquisition layer into the data and application service layer. The integration point is needed since the UWSNs operate with highly specialised communication protocols intended for acoustic communication and the data will have be provided to a gateway service via, e.g., 5G, WiFI, cabling or satellite communication.&lt;/p&gt;</description>

      <title>Messaging service for real-time data streams</title>
      <link>https://smartoceanplatform.github.io/page/messaging/</link>
      <pubDate>Fri, 19 Dec 2025 00:00:00 +0000</pubDate>
      <guid>https://smartoceanplatform.github.io/page/messaging/</guid>
      <description>&lt;p&gt;The messaging service of the Smart Ocean platform supports publishing data and subscribing to real-time data streams&lt;/p&gt;&#xA;&lt;p&gt;The messaging service is based on the publish-subscribe paradigm and the MQTT protocol. In this paradigm, data providers publish data topics while data consumers subscribe to topic in order to receive data published on the topic.&lt;/p&gt;&#xA;&lt;p&gt;The messaging service is comprised of two &lt;a href=&#34;https://console.hivemq.cloud&#34; target=&#34;_blank&#34; rel=&#34;noopener&#34;&gt;HiveMQ MQTT&lt;/a&gt; messaging clusters&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;An Ingestion Messaging Service for delivering data to the platform&lt;/li&gt;&#xA;&lt;li&gt;A Core Messaging Service for data transformation, forwarding and consumption&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;The data ingestion service receives data in formats determined by the data sources and a transformation to the SmartOcean data format is performed prior to publishing the data on the core messaging service for further processing.&lt;/p&gt;</description>
