The user can customize the site definition in deployment which is in Microsoft windows and share point services, by coping an existing site these can be customized. The one thing that has to be kept in mind is that the changes that are made in the original installed files itself can be overwritten when the installation for the updates and for windows share point services, to make the changes internet information services can be reset. To know what an image conveys the visually impaired users completely depend on attractive text description, of what an image conveys, by using an alternative text the user can provide the same information which is provided by the text description.

By setting alt attribute the customization of the alternative text displays image can be conveyed. For the home logo the user can set the alternative text which is used for the home logo, the other images also can be modified, the text logos can be customized within the ASPX pages of a site definition, the home page can be customized with default.aspx, to view all the items in a page it can be customized in allitems.aspx, in order to create list item newform.aspx can be customized.

When the user creates the site definition the new site definition which is created by the user includes one default.aspx file, each site is created is instance for other list types, for every image the user has to define an alt attribute, alternative text can be used when an image serves as a hyper link, in order to modify the alternative text that is used for the image web part on the homepage can be alternated. By clicking modified shared page on the home page, point to add web parts and then the user can click browse to image web part with a content editor web part.

Adding background music to the web site is an exciting thing for every user, but many people worry about the slow loading of the pages and the size of the large files, without having large files the back ground music can be added to the web site these can achieve professional results. There are many ways of adding back ground music to the web site, to create the sounds using the instruments midi files can be used. It has got a problem that is most sound cards do not have any decent sounds. Since no two sound cards are alike so the result is unpredictable.Midi sounds as if the sound is coming from the cheap Casio keyboards, it is very small file size and it is very easy to implement, for the professional sounding and recording the wav file format can be used, the sizes are very large by using a file of low quality also the user can have large files, but the thing is that it takes long time to load the music, that is worst thing that happens to the sites, implementing the web page on a wav file is easy, just by adding line to the HTML code it can be done. It has got many quality levels, and it is very easy to implement they are very large in size the wav files do not loop.Flash is another file that is used for the adding back ground to the web page, if the user has a program that can create flash files then there is lot of flexibility in adding sound to the web site. Flash will allow the user to import wave and as well as mp3 files, it has got small file sizes, the user need to buy expensive flash software to create flash files.

As the standard image PNG was designed to replace GIF as the standard image format for the comprehension on the internet. The comprehension of PNG is better than GIF it has got full alpha transparency and gamma correction, the common browsers support PNG, and it is recommendation of the W3C. In one way the binary transparency is equal. Research is done taking three simple graphics the first one is the palate of 64 colors, and the next one with 128 colors and these are compressed in three different ways, in Photoshop when compared the pictures with one another png image is larger than the gif.

The digital maps which are displaying various measurements can be generated in GIF or PNG. The poor PNG support of Photoshop is a major problem, GIMP is a program which is excellent. Gamma corrections refer to the ability to correct for differences how computers interpret color values. The two factors of it are it predicts an image; it has also got the ability to match the colors. One of the biggest advantages of PNG is the ability to support full alpha transparency. Internet explorer for windows does not support full alpha transparency. The two configurations on the left, and below use the same image against different backgrounds.

The user should make the decision whether to use PNG or not png does not provide proper support to wide spread applications, png is not compressed in Photoshop as gif’s are compressed in Photoshop, gamma corrections refers the ability to correct for differences in how computers interpret color values, it has got the ability to match the color sources on a single page, all versions of Photoshop from 5 upward have a known bug that will incorrectly save gamma values.

Abode is the greatest software for all the time, though many consumer were attracted to the new features, like Dreamweaver CS3, illustrator CS3, Photoshop CS3, the people those who have participated in testing process of the apps give importance to Abode CS3, with the file name FLVPLaybackcaptioning is in the captioning components and it is tucked in with the video components when flash CS3 is installed, the component will not work solo it has to work with the flvplayback component, the meaning of it is there should be instances of both components on the stage for this component to work.

In order to make the component work the user has to watch the video and note the times and the text, and the user has to create one documents of XML and next the user has to link the XML document to the captioning component in flash, this is very simple to use, after doing everything that are mentioned above the user has to add captions using both methods to the same video, gathering of the format is a bit different from writing an XML document, the user can set the styling for text, but each caption needs to have an end and start point. When the caption appears it should have begin attribute, the begin attribute determines when the caption should appear.

The controls cover the caption when the user uses over series of skins, now the user has to add a new layer and he has to name it “caption” when the user selects the caption layer he has to select a text tool and text box should be drawn out under the video on the flash page. Font and point size should be selected.

The well known PNG format is APNG it has got many features, it supports for animation and in additional to it has got 24 bit images, and eight bit transparency, the ordinary frames with two additional data chunks is contained in an APNG file, for all APNG data there are certain rules, they are in glance the size of the total APNG is the size of the first frame, an aCLT chunk must appear before any IDAT chunks and fCLT  chunk must appear before the IDAT chunks. Before the entire image is read APNG is designed to allow incremental display of frames. So when it is done the few errors will not be appeared until the part way through the animation.

If any error is found then decoders should discard all subsequent frames, when it happens the user has to stop the animation and has to revert to display the default image. An error which is detected by decoder should display the default the default image, many times an error message is displayed to the user, the structure of APNG is stream is normal PNG stream, it has got three additional chunk types they describe the animation and provide additional  frame data, at the beginning of the each play the output buffer should be completely initialized to a fully transparent black rectangle.

As the first frame of the animation the default image may be included, it is done by the presence of a presence of a single fcLT chunk before IDAT, and at the beginning of the each play the output buffer must be completely initialized. The entire boundaries are specified with width and parameters of PNG IHDR chunk, each frame is identical for every play and so it is safe for applications to cache the frames. 

The audio and video podcasts are not accessible to blind or deaf individuals, about the accessibility of emerging technologies has been an issue which many of the innovators are finding to solve, there are two ways in making the podcasts more accessible. Podcast transcription services are closed and captioning services are available, the accessibility of podcasting is not only to the podcasting individuals that are with disabilities but it permits who like to receive the information in a different media there are many benefits in the accessibility of podcasting which the user has to consider, the issue of accessibility of podcasting is very large.

The accessibility of podcasting can be done easily if the user wants to make the podcasting more accessible then there are three different and main groups which has to be considered, first group is seeing impaired the second is hearing impaired and the next one is sight and sound impaired, there is solution for every problem that occur, podcast transcription can be done the user has to consider transcribing podcast and should be considering while posting a link during the podcast, if the person still finds difficulties in doing so then he has to publish a blog of transcription.

The expensive thing to do is captioning of the video of podcast, the complaint on this one is that the words are too small to read there are captioned podcasts  which are not agreed, if the two versions are published of the podcast by the user so the people can choose which they want to hear or read, minor sight and hearing issues can be taken care with volume control and background noise, and the large text captioning can be used in the silent film idea, it is very good solution. 

For the integration of data there are many techniques of using SQLXML and .net the sql client data provider supports execute xml reader it can consume directly the result of it to do the xml query the user can use xml directly, the role of XML query in reinventing the wheel is very large the overlap between the xquery and xslt is too great for W3C to recommend both as separate languages if the XSLT is not considered enough as an XML query language then its development should be built from the same and semantic syntactic base as XSLTThe most overlap between XML query and XSLT is done by the sharing use of XPath 2.0, even Xpoint also took a similar approach layering itself on Xpath 1.0 at first it seems reasonable, XML query is characterized as a subset of XSLT there are no template rules and no abbreviated Xpath  so the innovators think that this should be model upon XML query, if a subset Xpath or XSLT is necessary for the query implementations to work  then section 2.11 of the XSLT 2.0 would state XSLT 2.0 and this could improve the efficiency of the transformations on large documents.XML query processes in four stages first of all the user has to identify the documents that will be searched, the second thing to do is applying query conditions to include or exclude each, then the user has to add the specified fragments of each document to intermediate results and finally the user has to present output. XSLT does very good job in 2and 4 and a proper job on 1, XSLT and Xpath has got few things in common they are selecting nodes and generating the result tree.

In the beginning the access key attribute sounded like great idea, the most important thing that it does is attaching key board shortcut to HTML documents and this allows users to quickly jump to the different parts of the page without using mouse, there are many web browsers that do not prevent short cuts assigned through an accessible key attribute. The HTML access key is used to assign a key board short cut to a link, the main intentions of it is to make key board users to quickly navigate to different parts of a web page.

When the access key is triggered then the browser follows a link and it submits form. Certain times two or more elements share the same accessible key at that time it depends on few things mainly Firefox steps through the elements that share the same value when the user triggers the keyboard shortcut repeatedly, and when this is done only the elements that are normally activated like links and form buttons only receive focus, safari also activates the last of the elements that share the same value, opera will activate the first of the elements that share the same value.

Firefox uses ALT+shift as modifier keys to invoke access key alt key is used as a modifier key to invoke access key by Microsoft’s internet explorer, alt key is used by Mozilla as the modifier key to invoke the access key, Linux operating system uses the control key as the modifier key, and opera allows exposition of all access keys. Actually the definition of access key itself is bit confusing many of the users may not be knowing about how to use it so the solutions that are stated above might clear few doubts regarding it.

The most advanced technology is based on style sheets and frames in the web extension process, these cascading style sheets are an attractive web design with extension, in order to control the lay outs and make the pages easily available cascading sheets are used. Difficulties with older browsers also can be overcome with cascading style sheets. CSS makes many fronts and margins to be modified and with the use of CSS those pages look attractive. Since it beautifies the pages it is very important in the web designing process. CSS has got very attractive features and the recently the technologies also made sure that the web design with CSS is more attractive and it is very easy to read compared to the older browsers.

Before the CSS was used in the web design there were multiple doubts and totally the web design was a confusion, after CSS is used in the web design there is no more confusion and these cascading style sheets defined the presentation of each element, and the whole set of elements are also can be defined with cascading style sheets. There are many advantages in using cascading style sheets these style sheets separates content from presentation, in general if the user wants to change the margins on all pages in the site then the user has to change every page but in CSS if the user changes the default style then the margin of every page is changed.

In the web design the frames are bad though they help site navigation the problems remain the same, it is very difficult for the pages to be book marked so it was difficult to specify the set of frames as link destination but cascading style sheets have provided the elements that are fixed and absolute position. 

The ontology web language is language that is set and designed for the use of applications and to process the content in information, the aim of ontology web language is wide not just presenting information to humans. Ontology web languages describe the ideas in domain so it could be understood by software, ontology web language expresses the meaning of semantics in a better way compared to XML, RDF for all these reasons it could even go beyond in making the machine interpretable content on the web. The semantic web helps in defining the meaning and it enables the computer better.

The ontology web language serves with examples, technical examples, references and diagrams,  this ontology web language is designed by the W3C web ontology working group, and it has high level abstract syntax, as the recommendation of the W3C candidates the world wide web consortium has issued web ontology language, the recommendations of the candidates has paved way for implementations that indicate that document has been reviewed by all other W3C working group, with this web ontology language the specifications are stable and appropriate. OWL is a language which enables rich integration and interoperability of data.

Early adopters are bioinformatics and medical communities’  corporate enterprise and governments, owl enables descriptive applications that include managing web portals, collections management and content based searches. In order to process more machines and make it reusable owl is an important step for making data on these applications. Ontology web language is specified in six documents they are owl over review, owl semantics and abstract syntax, and owl use cases and requirements and owl test cases, owl helps in the web languages and with this ontology web language there are many features this owl has made the web languages easy to understand.
