</span><span style="color:#1F497D">Microservices are a software development technique —a variant of the service-oriented architecture (SOA) structural style— that arranges an application as a collection of loosely coupled services. In a microservices architecture,
services are fine-grained and the protocols are lightweight. / Wikipedia</span><o:p></o:p></p>
<p class="MsoNormal"><span style="color:#1F497D"> </span><o:p></o:p></p>
<p class="MsoNormal"><span style="color:#1F497D">The proposal is to review these micro-services and compare them to the OAIS-IF services that we have been considering. The columns “Derived Micro-service” and “Derived Description” contain modifications to the
original text, often using OAIS terms. </span><o:p></o:p></p>
