|**[[ddsf:public:guidebook:06_append:01_family_of_standards:04_gate:ddsweb]]**|defines a platform-independent Abstract Interaction Model of how web clients should access a [[ddsf:public:guidebook:06_append:glossary:d:data_distribution_service_dds]] System and a set of mappings to specific web platforms that realize the [[ddsf:public:guidebook:06_append:glossary:p:pim]] in terms of standard web technologies and protocols.|
|** [[ddsf:public:guidebook:06_append:01_family_of_standards:04_gate:ddsopcua]]**|defines a standard, configurable [[ddsf:public:guidebook:06_append:glossary:g:gateway|gateway]] that enables [[ddsf:public:guidebook:06_append:glossary:i:interoperability|interoperability]] and information exchange between systems that use DDS and systems that use [[ddsf:public:guidebook:06_append:glossary:o:opc_ua]].|
|** [[ddsf:public:guidebook:06_append:01_family_of_standards:04_gate:ddsxrce]]**|defines the [[ddsf:public:guidebook:06_append:glossary:p:protocol|protocol]] used by a resource constrained, low-powered device (client) to publish and subscribe data to a [[ddsf:public:guidebook:06_append:glossary:d:domain_dds|DDS Domain]]. The XRCE protocol connects the XRCE client to a DDS Agent that acts as the gateway to the DDS Domain.|
