An explanation of how to add various types of multimedia objects to your Connexions content. Examples of some of the more common multimedia objects are included.



Connexions modules can contain many different types of embedded multimedia files. This document explains how to use these elements to create media-rich modules. Though you are welcome to skip ahead at any time, we strongly recommend that you read the sections on Accessibility, Uploading Media Files, and Embedding Media Elements in Your Module before moving on to a specific medium as these sections cover several important aspects common to all media types.

This module contains a number of code examples designed to illustrate specific aspects of the CNXML language. As a result, these code snippets will not always take advantage of all of the available options and attributes for every element. Feel free to experiment with different combinations and structures as you build your modules to learn how these options can enhance your module's multimedia content.

Connexions supports the use of any media format that has a valid MIME type (see this page for more information). In order to take advantage of the media, however, end-users must also have any necessary software and/or browser plugins installed on their browsers. For this reason, it is advisable to stick with common file formats when authoring in Connexions. This module provides a number of CNXML code snippets that cover several typical use cases, though this list is not exhaustive.

If you need assistance adding multimedia to your modules, have questions about an object not listed in this module, or have any other authoring issues that you need help with, please contact Connexions technical support at techsupport@cnx.org .

Making multimedia accessible for all users

It is important for authors to remember that not all users are able to experience media the same way. Visually impaired users will not be able to view graphical content, while those hard of hearing will not be able to experience audio content as intended. As an author, should always strive to make their content accessible to as many audiences as possible; in addition to allowing more users to enjoy and benefit from your work, you will also make it easier for the many organizations required by policy or law to meet accessibility standards to use and adopt your content.

Alt text

Alt text allows authors to provide a short description of the visual content of a media element. These descriptions can be read by screen reading software packages used to assist visually impaired users. Keep your alt text short but descriptive; imagine somebody trying to describe an image you cannot see and think about the information you would find most important. A few tips:
  • Don't be redundant. The user is already aware that this is an image, so don't start your description with "This image is . . . " or "A picture of . . . "
  • Keep it short and sweet. Describe only the relevant aspects of the image; for example, it might be important to describe the subject of a photograph as having freckles, but it is probably not necessary to count how many freckles she has on each cheek.
  • Use correct grammar and spelling. For the majority of users requiring alt text descriptions, this content will be read out loud; these descriptions should adhere to the same quality andstyle standards used elsewhere in your work.
Alt text is required for all <media> elements.

Jeffrey Reply
sure. what is your question?
okay, so you have 6 raised to the power of 2. what is that part of your answer
I don't understand what the A with approx sign and the boxed x mean
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
I'm not sure why it wrote it the other way
I got X =-6
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
oops. ignore that.
so you not have an equal sign anywhere in the original equation?
is it a question of log
I rally confuse this number And equations too I need exactly help

or infinite solutions?
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

Yes, Nanotechnology has a very fast field of applications and their is always something new to do with it...

good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
I'm interested in Nanotube
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
can nanotechnology change the direction of the face of the world
Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
