The IoT landscape is characterized by a fragmentation of standards, platforms and technologies, often scattered among different vertical domains. To prevent the market to continue to be fragmented and power-less, a protocol-independent semantic layer can serve as enabler of interoperability among the various smart devices from different manufacturers that co-exist in a specific industry domain, but also across different domains. To that end, the SAREF ontology was created in 2015 with the intention to interconnect data, enabling the communication between IoT devices that use different protocols and standards. A number of industrial sectors consequently expressed their interest to extend SAREF into their domains in order to fill the gaps of the semantics not yet covered by their communication protocols. Therefore, the SAREF4INMA ontology was recently created to extend SAREF for describing the Smart Industry & Manufacturing domain. SAREF4INMA is based on several standards and IoT initiatives, as well as on real use cases, and includes classes, properties and instances specifically created to cover the industry and manufacturing domain. This work describes the approach followed to develop this ontology, specifies its requirements and also includes a practical example of how to use it.

SAREF4INMA：针对工业和制造领域的SAREF扩展

物联网领域的特点是标准，平台和技术的碎片化，通常分散在不同的垂直域中。为了防止市场继续变得支离破碎和无能为力，与协议无关的语义层可以充当不同制造商的各种智能设备之间的互操作性，这些智能设备共存于特定的行业领域，而且跨越不同的领域。为此，SAREF本体于2015年创建，旨在互连数据，实现使用不同协议和标准的IoT设备之间的通信。因此，许多工业部门表示有兴趣将SAREF扩展到其领域，以填补其通信协议尚未涵盖的语义空白。因此，最近创建了SAREF4INMA本体，以扩展用于描述智能工业和制造领域的SAREF。SAREF4INMA基于几种标准和IoT计划以及实际用例，并且包括专门创建以覆盖工业和制造领域的类，属性和实例。这项工作描述了开发该本体所遵循的方法，指定了其要求，还包括如何使用它的实际示例。
