Global FORMAT setting

The header and format parameters might also use variables rendering the dc, image and content namespace information. Note, that only bits of interest have been implemented so far and those namespaces might not be implemented fully yet.

Rendering the dc namespace

The following variables are extracting the dc namespace info, that could be used in header and format. Nnote, that some of the variables are already used above. This is done by purpose to use different feeds with the same formating parameters. If there's a conflict the non-dc tags have higher precedence, i.e. a <title> content </title> is prefered over <dc:title> content </dc:title> .

  • $title: channel/article title (dc:title)
  • $creator: channel creator (dc:creator)
  • $subject: subject text; this will also add an image according to the subject hash list, see above (dc:subject)
  • $description: ... (dc:description)
  • $publisher: the channel/article publisher (dc:publisher)
  • $contributor: ... (dc:contributor)
  • $date: ... (dc:date)
  • $type: ... (dc:type)
  • $format: ... (dc:format)
  • $identifier: ... (dc:identifier)
  • $source: ... (dc:source)
  • $language: ... (dc:language)
  • $relation: ... (dc:relation)
  • $coverage: ... (dc: coverage)
  • $rights: ... (dc: rights)

Rendering the image namespace

An image:item is converted into an <img> tag using the following mappings:

  • src: image url (rdf:about attribute of the image.item tag)
  • alt: image title (title)
  • width: image width (image:width)
  • height: image height image:height)

Rendering the content namespace

The variable $content is refering to the <content:encoding> content </content:encoding>.

In 2009, when a group of sports competitors were out training in the mountains of Park City, Utah and trying to use an iPhone in minus-20 degrees with much difficulty and pain, the idea for the eGlove was born. Six years later, eGlove is an award-winning leader in touch screen technology gloves for outdoor sports and everyday warmth.

With a wide range of high-end sports gloves for running, cycling, riding, walking, ultras, snowboarding and skiing, eGlove is so passionate about the quality and perfection that every glove is brutally tested before launch to ensure it is warm, providing maximum comfort and delivering total accuracy when using any touchscreen device. With a current product return rate less than 0.5%, you know they are serious about their products.

eGlove is eager to develop partnerships and is open to anything that increases brand awareness and drives higher unit sales.

The Internet has changed everything, as you might have noticed if you've not been living underneath a rock for the past decade or so. Because information of all shapes and sizes is so readily available to the average consumer, it's completely changed the nature of the background checking business. Whereas once checking backgrounds required a lot of legwork, now most people can successfully search someone's background from the comfort of their own home.

If you've always secretly wanted to become a spy, then perhaps background screening could be an exciting and rewarding business for you. But how do you get started? Luckily, we've found an excellent opportunity for a budding private sleuth entrepreneur to get started with.

What Does a Background Check Entail?

Although it's incredibly unlikely that you've never had a background check performed on you, it's still possible that you might not know what a background check actually entails. Typically, a background check will be requested for an individual in situations that involve loans, housing, firearms and other high-value or high-risk transactions.

The purpose of these background checks is to establish a history for the person being examined, and depending upon the purpose of the examination, different things will be focused upon. When renting an apartment, for example, a landlord might want to look into a potential tenant's criminal background and credit history. When purchasing a firearm, a background check will look into everything from traffic violations and previous addresses to aliases and credit scores.

In all of these cases, someone needs to actually sit down and do the research - which is where the business opportunity comes in. While the Internet has made much of this information available at the click of a button, most of it is not centralized in one place. For that reason, a qualified person will have to perform the search, which, depending upon the thoroughness of the background check requested, will actually be more akin to comprehensive research than anything else.

A Good Place to Start

If getting into the background checking industry sounds like the right thing for you, then check out the Background Screeners of America. First and foremost, it should be noted that this business is a member of all the major trade organizations in the industry, including notable ones like the Society for Human Resource Management and the National Association of Professional Background Screeners. Because of these credentials, you can be assured that it has an established reputation within its industry.

The prospective entrepreneur will receive comprehensive training on how to accurately and thoroughly conduct background checks. In addition to this, the invested entrepreneur will receive training on how to generate clients and profits. They will also be granted access to Background Screeners of America's staff, who can assist with all of the work required to conduct a background check. With that kind of support, it's easy to see how a motivated entrepreneur can truly make this business work.

RELATED: TIPS AND TRICKS FOR RUNNING A BUSINESS OUT OF YOUR HOME 

Finally, one thing to consider is that it will be a primarily home-based business. Most of the research required to conduct the background checks can be done through the Internet, which means that the prospective entrepreneur will have minimal overhead expenses to factor into the cost. When you combine this with the lack of fees that are assessed by Background Screeners of America on their franchisees, then you have the potential for generating some real profits.

In order to get started with this business opportunity, you'll need to be prepared to make a startup investment of $19,950. That may be a little steep for some, but it's worth it in order to get involved with a business that already has an established reputation within its industry.
