What is XML?
Extensible Markup Language
XML or Extensible Markup Language is a
universal method of transferring data so that any webpage can request and
display content from an outside source when using dynamic scripting
languages in your web pages.
Dynamic scripting languages insert
instructions into HTML tags to
process XML data and display it on
the page. The data is requested by
user interaction with the browser
and is called a request when a
search button is clicked.
The data is based on the requested
parameters and a response is
returned to the affiliate server.

Data Flow Example
What is XML?
XML consists of data which is inserted
between datafield tags known as elements
XML data from our database is translated
into extensible markup (tag-based element
rather than a database field)

What is XML?
By giving the data a universal tag-based reference using
XML, any webpage can be coded to request the data
and write it to it s own page rather than linking to a

What is XML?
Dynamic Data
XML data, delivered with website scripting languages, is called to the
page and is dynamic or on the fly .
The page is not written until the request or search for data is made and
the data is sent back to the web page to be used as the text in the
layout.
The browser receives the data that is requested and uses the HTML
instructions to write the XML data into the page design at that very
moment.

What are Web Services?
Data Transportation
Web Services is another way of transporting XML
data across the web.
A Web Service is a library providing data or
services to other applications over the Internet.
A service is called by using internet protocol
standards such as SOAP over HTTP. Each
"service" exposes a business functionality and
means of interacting with a dataset at run-time.

What are WebServices?
Object Oriented Transmissions
The method of invoking a web service will depend on the programming
language used.
Java or .NET utilizes inherent
language functionality to compile
source code along with special
server configurations to make the
XML Web Service request and then
process the results.
Other methods may use SOAP
directly within the document object.

How is WebServices different from XML?
Methodology
Data is transmitted with server-side source code instead of
within web page scripts.
The request is coming from a separate source file stored on the
server rather than inside the web page scripts.

Advantages of using XML
Content, Design & Marketing Control
Write our product content to the affiliate s own web pages.
You do not have to work within the confines of the affiliate template pages.
You have more options than the use of your own headers and footers.
You can organize the content and search results to fit your own
merchandising, target audience, and demographics.

By using XML, affiliates create more of
their own content which can be used
to greater capacity with the search
engines and other marketing efforts.
You also have the ability to integrate
other appropriate content with our
data.
The original/additional content will
improve search engine traffic,
relevancy, and alter duplicate content
which therefore improves rankings.

you engage the user
to build your traffic?

Keyword Optimization
You can utilize keywords for your
search engine market on each of
your own pages to your best
advantage.
All the content appears as if it came
from the affiliate and not another
source.
This gives you tremendous flexibility in
your marketing and online presence.

Version Maintenance
We maintain up to 2 versions of interface
code at a time. Required changes may
occur once or twice a year.
At the end of the older version s cycle, this
code is removed from the system and
can no longer be accessed. This insures
all affiliate code and data are current and
creates an efficiently managed platform.
The affiliate is notified by XML
newsletters in advance of the upcoming
schedules and you may typically have up
to 6 months to complete any updates.

Who is NOT a good candidate for XML?
Affiliates who do not have technical or financial resources to develop,
purchase or maintain an xml website. Remember you receive our
application and all programming logic for free when you use your
affiliate template. When you use the data interface, all you receive is
data. It is up to you to create any and all logic necessary to manage
your page functions, control user input and activity, and workaround
common user errors.
Affiliates who do not expend time or effort on marketing, search
engine optimization or market research expend a lot of time and effort
for no chance of return on investment.
Any affiliate can find a way to utilize data integration, however,
because of the effort needed to do so, it s those who actually work
their sites, have a sense of professionalism and a good
understanding of the internet who will benefit the most from the time,
money, and energy needed to create such a site.

Where can I find the XML documentation?
https://www.ian.com/xmldocs/main.jsp
If an affiliate has a developer, or
others, who need to access the
documentation to create his application
but does not want others to have his
affiliate account login, we have a
dummy account set up for this purpose.
You may use this login information in
both the XML Documentation Center

There are a few ways
to parse the data to
the page but the most
common is by using
Extensible Style
Language (XSL)
which introduces the
xml data into the html
display instructions.
Here is a sample of
parsing the data with
XSL to display the
Hotel Availability to the
page.
XML is dynamic data
XML is updated from the
source each time accessed
XML data is written to a
webpage template file each
time it is accessed
XML uses another
programming language to
parse the data into html
format

The response is still returned
with an XML format but is
handled differently by a Web

Is there an archive of XML Newsletters and System Notices?
With the archive of
Newsletters, System

found in the Site Map,
you can always refer
back to circulated
publications and the date
it was announced.

Where do I sign up for XML Access?
On the homepage, find the
Section pointing to Managing
Your XML Access.
This section provides links to
all pages for maintaining the
affiliate s access.

27
Follow the navigational path
How do you sign up for XML?
Accounts that request access through the XML
application form are now automatically validated
with XML contract language so that no additional
paperwork or additonal legal approval is required.
The online contract acts as a digital signature and
validates that you agree to all legal terms of use.
Any negotiated contracts you re working on will supersede any
online contracts once completed.
Here is a direct link that can be used to apply for XML access
with immediate contract language.

What things are not allowed?

XML Access is for Active CIDs only
1
The partner must fill out the XML application which includes info we need to activate
your account. Missing info delays your activation.
http://12.14.173.100/xmldocs/xmlAccessForm.asp
2
The application includes minimum required info to set up access:
pre-approved agreement to XML language while we re waiting for a negotiated contract to be
completed
Your own CID
IP addresses of your requesting server
Used to authenticate access with your CID
Specific XML Products you want activated (hotels, car, air, road trips)
Additional info that helps us manage your access
URL where XML is expected once the API is completed
Used for site reviews and audits
Email addresses who should receive any critical XML notices or update messages
Insures you know when updates are needed to your API and alerts you to scheduled downtime
Phone number we can use to contact you in the event of a problem

What is the Approval to Go Live?
Once you have completed your program and is ready to go live it is crucial that we
review the site for live approval against our Mandatory Requirements Checklist.
https://www.ian.com/xmldocs/checklist/checkListHome.shtml
The review process verifies
any required/legal items are present throughout
all pricing and text is accurate
insures the site returns a test booking
verify the test booking and confirmation text for accuracy against supplier charges
We compare the affiliate results to the same search results on Travelnow.com
These guidelines are there to protect partners in the event of any customer disputes and
chargebacks by the hotel when proper pricing is not displayed or policies are not properly
informed.
It is in your best interest to collaborate with us in the final step.
