To promote both interoperability between resourceconstrainedWeb service implementations and interoperability with more flexible client implementations,this profile identifies a core set of Web service specifications in the following areas:Sending secure messages to and from a Web serviceDynamically discovering a Web serviceDescribing a Web serviceSubscribing to, and receiving events from, a Web serviceIn each of these areas of scope, this profile defines minimal implementation requirements for compliantWeb service implementations.1.1 RequirementsThis profile intends to meet the following requirements:Identify a minimal set of Web service specifications needed to enable secure messaging,dynamic discovery, description, and eventing.Constrain Web services protocols and formats so Web services can be implemented onperipheral-class and consumer electronics-class hardware.Define minimum requirements for compliance without constraining richer implementations.1.2 TerminologyThe key words “MUST”, “MUST NOT”, “REQUIRED”, “SHALL”, “SHALL NOT”, “SHOULD”, “SHOULDNOT”, “RECOMMENDED”, “MAY”, and “OPTIONAL” in this document are to be interpreted as describedin [RFC2119].1.2.1 Notational ConventionsThis specification uses the following syntax to define normative outlines for messages:The syntax appears as an XML instance, but values in italics indicate data types instead of literalvalues.Characters are appended to elements and attributes to indicate cardinality:o "?" (0 or 1)oo"*" (0 or more)"+" (1 or more)The character "|" is used to indicate a choice between alternatives.The characters "(" and ")" are used to indicate that contained items are to be treated as a groupwith respect to cardinality or choice.The characters "[" and "]" are used to call out references and property names.Ellipses (i.e., "...") indicate points of extensibility. Additional children and/or attributes MAY beadded at the indicated extension points but MUST NOT contradict the semantics of the parentand/or owner, respectively. By default, if a receiver does not recognize an extension, the receiverSHOULD ignore the extension; exceptions to this processing rule, if any, are clearly indicatedbelow.XML namespace prefixes (see Table 1) are used to indicate the namespace of the element beingdefined.wsdd-dpws-1.1-spec-os 1 July 2009Copyright © OASIS® 2009.
