Before I move on to those topics , let 's review how SOAP and WSDL handles data encoding while they work .

用于使用和创建服务的大多数SOAPAPI要么显式地、要么暗示地指定了它们所期望的数据编码以及它们所支持的传输。

Most SOAP APIs for both consuming and creating services will either explicitly or implicitly specify the data encoding they expect and the transports they support .

当时的想法是要使服务和客户机的编写工作更加容易，简单的服务和客户机只需同意在向XML转换时遵守一套数据编码规则即可。

The idea is that simple services and clients would simply agree to follow a set of rules for encoding data to XML in order to make writing services and clients easier .

当对SOAP规范的需求被提出时，许多人都认识到了为SOAP信封内的数据编码制订一些标准规则的需要。

When the requirements for the SOAP specification were drawn up , many people saw the need for standard rules for encoding data within SOAP envelopes .

GML已经成为事实上的空间数据编码、传输、存储和发布的国际标准，大量GML格式的空间数据开始涌现。

GML has become the defacto international standard for spatial data encoding , transmitting , storing and distributing ;

SOAP在传输方面的可扩展性经常需要进行导致兼容性问题的隐式假设，有效负载数据编码方面的可扩展性也是如此。

Just as the extensibility of SOAP with regard to transports often causes implicit assumptions which create compatibility problems , so does this extensibility with regard to payload data encoding .

由于SOAP与传输无关，并且不强制使用哪种数据编码格式，所以我们不能仅仅知道一个服务支持SOAP，还必须了解有关该服务的其他信息。

Since SOAP is transport independent and does not enforce a data encoding format , one must be aware of more about a service than simply that it supports SOAP .

GML语言是开放地理信息系统联合会制定的基于XML的空间数据编码规范，对于GIS互操作的研究有重要的参考价值。

Geographic Markup Language ( GML ) is a specification for encoding spatial data formulated by Open GIS Consortium , and it plays an important role in GIS interoperability studies .

USB transfer module design , including hardware circuit , software flow , transfer pattern , data coding and packet format . ⑤ Drivers design , including communication protocol and software module .

我们还需要理解WSDL的特定扩展、发送SOAP信封时使用的特定传输和服务所需的数据编码以及其他信息。

Instead it involves , among other things , understanding particular extensions to WSDL , the specific transports over which to send SOAP envelopes , and the data encoding expected by the service .

本文深入研究了DICOM标准协议的各个方面，特别是信息对象定义、信息模型、服务对象对类、数据编码等部分。

由于GML自身的完善，以及其独有的优势，GML已经成为空间数据编码、交换的国际标准。

Because GML itself is perfect , and its unique advantages , GML has become the spatial data encoding and exchange of international standards .
