Interview Questions.

Question 1. What Are The Goals Of Mathml?

Answer :

The important aim of MathML is to permit arithmetic to be served, obtained, and processed on the Web, simply as HTML has enabled this functionality for textual content. In greater detail, MathML is meant to:

encode mathematical cloth appropriate for coaching and medical conversation at all tiers.
Encode each mathematical notation and mathematical which means.
Facilitate conversion to and from other math formats, each presentational and semantic.
Permit the passing of statistics supposed for specific renderers and packages.
Help efficient browsing for lengthy expressions.
Offer for extensibility.
Be nicely suited to template and different math editing techniques.
Be human legible (though it's miles very verbose), and simple for software to generate and process.
Question 2. Who Are The Intended Users?

Answer :

MathML is meant for use (not directly normally) by means of each person from high-college mathematics students to academics and engineers in enterprise (These categories aren't necessarily distinct !). It additionally presents an interchange mechanism between packages processing mathematical representation in some form.

Question three. Why Do The Goals Of Mathml Go Beyond The Display Of Mathematical Expressions?

Answer :

The Web represents a essential alternate within the underlying metaphor for understanding garage, a trade in which interconnectivity and interactivity play important roles. The aim is to offer ways of speaking arithmetic which, similarly to rendering mechanisms, facilitate automated processing, searching and indexing, and reuse in other mathematical packages and contexts. This consists of contexts in which the underlying mathematical semantics are critical, including, for instance, in a distance mastering direction in Linear Algebra.

Question four. Mathml Is Verbose - I Edit Html By Hand With Emacs, And Mathml Looks Tedious To Read And Edit In Text Form?

Answer :

True! The verbosity of MathML is essentially a result of the WG choice to use XML because the base syntax. The motives for doing this consist of standardisation, availability of equipment and the general tendency of internet-based programs to apply XML as a service format. The drawback is that the encodings grow to be verbose for examples of any complexity, with ensuing necessities on equipment for MathML generation and manipulation.

Question 5. Backwards Compatibility - Why Has Mathml Not Reused Tex/latex, Or The Sgml Dtds Iso 12083 Or Aap Math?

Answer :

TeX and LaTeX are very broadly used for encoding mathematical expressions. However, they encode best the surface presentation of an expression, and do now not encode either semantic data or structural information. One of the WG desires is to provide a presentation mechanism that not best has the expressive capabilities of TeX, but additionally has enough facts in it in order that the presentation is:

accessible to the visually impaired;
able to doing a great activity of linebreaking expressions, considering the fact that the author cannot recognize the window length and font size wherein the MathML ought to render.
In addition to a presentation interface, it is essential to provide mechanisms for encoding mathematical semantic content, and controlling the interface among the embedded MathML fragment and the browser processing the containing page. We additionally taken into consideration that it became most advantageous for a report with embedded mathematical formulas to require simplest one type of parser instead of having a completely one-of-a-kind kind of encoding for the mathematics degree.

SGML DTDs are orientated toward whole files governed through one DTD in place of math fragments within Web pages. Apart from the paintings performed on the development of a 'Semantic Maths DTD fragment' in the ISO 12083 running group (now not part of the same old), existing SGML DTDs are presentation-orientated and absence guide for content encoding.

Question 6. Does The Verbose Mathml Syntax Takes A Long Time To Transfer Across The Net And Parse?

Answer :

By comparison with present image based totally methods of embedding math(s) in web pages, as an example GIF documents, MathML is tremendously quick to switch and method.

Question 7. Mathml Is Xml-based totally. Will The Browser Manufacturers Support Xml Fully? Will They Support Mathml Natively?

Answer :

Yes. Both Microsoft and Netscape have publicly declared aid for the XML advice. Some XML help is already available for IE four. As the browser manufacturers flow towards fuller guide of XML and the related fashion sheet requirements consisting of XSL which can be growing, guide for MathML becomes extra "local".

HTML 5 Tutorial J2EE Interview Questions
Question 8. Can I Embed Applet, Embed Or Object Tags Within Mathml?

Answer :

MathML is defined as an XML software, so there's no unique assist for embedding web objects inside MathML fragments. You can use APPLET and EMBED in the containing HTML web page to release an applet or plugin to render and process a MathML fragment or report.

Question 9. Does The Wg Still Intend To Develop A Short Form Input Syntax As Part Of Mathml?

Answer :

During the improvement of MathML it has emerge as clean that the requirements on input syntaxes vary so broadly that no single syntax will satisfy all customers. Various participants of the WG have evolved input syntaxes for his or her particular gear. The WG will offer technical recommendation to all folks who are worried inside the development of enter syntaxes for MathML-aware gear. Input syntaxes do no longer shape a part of the core MathML recommendation.

Question 10. Can I Overload The Presentation For Content Elements - For Instance, Can I Render As 'j'?

Answer :

Yes, you could use the semantics detail to attach a favored presentation (encoded in MathML presentation elements) as an annotation-xml.

Question 11. Why Is Math(s) Difficult To Render In A Browser. Microsoft Equation Editor Has No Difficulty Rendering Math(s)?

Answer :

The most important problem is that existing browsers don't offer an ok interface for third-birthday party software used to render consisting of plugins, applets or ActiveX controls. It is was hoping this can be solved as a end result on work on the next generation of HTML, DOM and CSS. In addition, with due recognize to a a hit piece of software, it cannot be stated that Equation Editor presents math presentation of the highest excellent or offers widely transportable outcomes.

As an instance of the sorts of troubles faced: The rendering code for an embedded piece of mathematics would love to apply a font length and family that matches the font used for the rest of the record's text. The plugin would love to control the vertical positioning for a math expression relative to the baseline of the text line in which the maths is positioned. The plugin would like to negotiate the height and width for the maths object in step with the distance wanted and now not have this fixed at authoring time. At gift, because of the shortage of a way of verbal exchange between embedded gadgets and the containing file, none of these requirements can be met.

A richer version for the rendering gadgets that compose a record, that doesn't treat plugins as impoverished remote loved ones will go an extended way to solving the problems.

Document Type Definition (DTD) Interview Questions
Question 12. Has The Unicode Consortium Accepted The Additional Characters Proposed By The Wg?

Answer :

Yes, all characters for which MathML defines entities are in Unicode due to the fact that version five.

XML Interview Questions
Question thirteen. Is Automatic Translation To And From Latex Possible? Is There Anything Available Which Does It?

Answer :

Generation of MathML from that in LaTeX documents (presentation and content material) is virtually feasible. Organisations operating in this problem encompass University of Western Ontario, and the AMS and SIAM.

Question 14. I Am A Content Provider (e.G. A Technical Publisher). (why) Should I Convert My Legacy Data To Mathml. How?

Answer :

The normal catch 22 situation with emerging standards: content is vain without equipment to create and manage it, and device vendors are reluctant to embark upon pricey trends whilst the marketplace for the product is unclear. However, there are already a number of gear underneath development.

Another vital trouble is the general trend of web-based applications towards using XML as a provider layout. MathML is the only 'wellknown' XML DTD for maths at the Web. Indeed, the running organization of the ISO 12083 committee considers that MathML can be the suitable 'plugin' mathematics module in a future modular version of the 12083 widespread.

Question 15. To What Extent Has Mathml Been Accepted By The Public And Industry Outside The W3c Math Wg And Its Friends? What Is Being Done To Further This?

Answer :

One of the duties of the re-chartered W3C Math WG is to promote the adoption of MathML in industry and academia.
