Introduction
Web Services are an every growing and highly useful method of viewing and manipulating geographic products, however there are several different ways in which to go about interfacing Web Services. SOAP (Originally Simple Object Access Protocol) and Representational State Transfer (REST) are two of the most recent and commonly used methods for interfacing Web Services. This essay will expand on what SOAP and REST are, compare the differences between them, and where possible relate their uses in the production of geospatial Web Services in Defence.
Aim
This essay strives to give readers a decent understanding of what SOAP and REST are, what and how they are used, and in what circumstances would one out-perform the other. It will

SOAP
SOAP first came into being in 1998 after being developed by Microsoft, however, it was not until SOAP version 1.2 was released in June 2003 that SOAP became a World Wide Web Consortium (W3C) Recommendation. This is also where SOAP ceased to be known as Simple Object Access Protocol and remains to this day as SOAP.
The main reason for its development was to supersede some of the older communication technologies that weren’t as effective when being used across the internet such as Distributed Component Object Model (DCOM) and Common Object Request Broker Architecture (CORBA)
SOAP is a communication protocol that utilises Extensible Mark-up Language (XML) to define the messaging framework and send messages from one application to another via other protocols such as Hypertext Transfer Protocol (HTTP) and Simple Mail Transfer Protocol.
It can be used in conjunction with Web Services Description Language (WSDL). This language is for the descriptions of web services and how to go about locating and accessing them. As with SOAP, WSDL is also XML based. WSDL is also a W3C Recommendation.
A SOAP message has four main elements. These elements are an; envelope, header, body, and a fault element. See Fig 1 for a visual breakdown of the SOAP message structure.

Fig 1 shows that the Envelope element is the root of the whole message and everything else is contained within the envelope. The Envelope
1. Explain the purpose of correctly receiving, checking and sorting mail and packages (both incoming and outgoing).
Standard conventions exist, like the use of “Dear Sir” that’s normally found at the beginning and the use of “Yours faithfully”. This is used because the person isn’t known because they might be a company. The use of “Dear Mr” and their name, and “Yours sincerely” will be used since the person is known. Letters tend to use standard layouts. These are usually blocked, semi blocked and indented. House styles can be presented for organisations. This could be things like fonts, formatting and etc.

Web application is the communication between client and server using HTTP protocol. Where the server is responsible for serving web pages. Client which is web browser, request web page from the server, receive the server response and display to the user. The user uses the client (web browser) to display the web pages, watch videos online etc. The client side and server side programming refers to the programming which runs at the specific side, the server’s or the client’s.
The flexibility of XML has made it the standard for the formatting and sharing of data via the web. XML data is easily transferable across machines and applications and is not constrained by the operating system of the host machine. This ease of translation enables XML to be transformed into non-XML formats for use with databases and their associated applications.
and across the network. Typically, this is a TCP/IP packet. This basically tells you what the format of the
Standards are important because it facilitates good representation of data and interoperability across systems. It also creates consistency in how we represent data. A large portion of utilizing data is around data-management and clean-up because data is inconsistently represented. The HL7 v2 standard helps achieve data standardization by having required segments in messages met so that all relevant information delivered can be interpreted clearly by the receiving party. HL7 v2 messages use a non-XML syntax that is based on segments separated by one-character delimiters. While not all segments are required, it is pertinent to have agreed on relevant segments, limit over-customization, and overcome implementation challenges. What type of systems exchange HL7
In this chapter, we will discuss the historical background on the objectives of Web services and security,and it will be touched upon the other subjects such us Confidentiality, integrity, authenticity services, authentication methods, Zero-Knowledge Proof protocols, and Diffie-Hellman key exchange is also discussed.
One characteristic of the mail box rule is indicating what form(s) of acceptance will be accepted. For example, a telephone call will be used as a form of acceptance.
Curtis et al (2001) noted that modern methods of promoting handwashing can be effective and cost-effective on a large scale. Studies suggest that soap is widely available, even in poor households in developing countries, although it is mostly used for bathing and washing clothes (Borghi et al, 2002). In rural India and Bangladesh, soap is often considered a beautifying agent or for the physical feeling of cleanliness which it gives, rather than being associated with the removal of microorganisms or health benefits (Hoque and Briend, 1991; Hoque et al, 1995).
