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>.

If you've ever locked yourself out of your car or house, you know the feeling - panic ensues. To make matters worse, maybe it's the middle of the night, you're in a remote location, or you only have an hour before an important work meeting. You need help and you need it fast.

Your first thought might be to call a local locksmith and try your luck, but there's a much better option. You need reliability. Call an established nationwide brand like 247Locksmith Services. Then, take a deep breath because help is on the way.

Did you know that in the US there are dozens and sometimes hundreds of people (in the big cities) who lock themselves out of their homes every day? It usually happens in the morning, when people go out to work, or in the evening, when they return home. Either way, this is a very unpleasant and sometimes even dangerous situation.

Do you think that this is an exaggeration? Here is another interesting fact: there is a home burglary happening approximately every 13 seconds in the US, and almost 30% of all home burglaries are committed through door or windows that were left unlocked. If we also consider the number of lost and stolen keys, you can easily see how a trivial case of losing or forgetting a house key can turn into a very negative experience, such as a break-in or a burglary.

Do you consider yourself a prospective entrepreneur? If so, in reality, you can do just about anything that sounds interesting to you that will make you money. In terms of business opportunities, the world is your oyster. You just need a solid idea to get started and the follow-through to make it happen.

It takes a special type of person to be an entrepreneur - someone who dreams of being their own boss and wants to take complete control over their financial well-being. It's scary and requires a lot of responsibility. But you're ready for the challenge, and we're here to help.

There are plenty of business opportunities for you to consider, but we've chosen five of them to highlight. Here is a brief summary of each of them:

Home Based Business Opportunities 

Do you want the freedom and flexibility that working from home provides? Well, then you are in luck, as there are literally thousands of different home based business opportunities out there. In fact, you might find that the most difficult part of beginning a home-based business is actually choosing one from among the many. You can start a business from scratch by becoming a consultant, financial planner, writer&hellip you name it. The possibilities are really quite endless. Or you can hook up with an established company like Matco Tools, Just Between Friends or 1-800-GOT-JUNK. Take your time and do your research to find the perfect fit.

Online Business Opportunities

Why spend thousands of dollars on a traditional brick-and-mortar business location when you can get an online business up and running for a fraction of the cost. Regardless of your area of expertise, there is a plethora of opportunities out there for you to make money online. Someone, somewhere is in need of your skills and talents - and they're willing to pay you for it. Motiply, Background Screeners of America and Perks Nearby are just a few examples of online business opportunities, among many others.

Affiliate Marketing 

For several years now, affiliate marketing has been one of the fastest-growing business opportunities. What's great about becoming an affiliate marketer is that you don't have to create any products yourself. As an affiliate marketer, you just link up a buyer and a seller, and then you take a commission on the sale. Say you're a fitness guru who runs a successful fitness blog. You can supplement the income you're already earning through banner advertisements by entering into an affiliate relationship with a fitness-related business. There are so many affiliate marketing opportunities, however, that you should be selective. Try to focus on one or two relationships when you're starting out. Do what you can to meet with success in those relationships, and keep track of what strategies are working and what aren't.


In order to expand the reach of their products, many companies take advantage of reseller programs. They partner up with a network of resellers who handle the sales and distribution of their products and services. In some cases, a reseller will be responsible for holding onto stock that they will then sell to their customers. In other cases, the company producing the product will handle all the order fulfillment. Because of this, there's a lot of flexibility within the reselling model, and it's very likely that you'll be able to find an arrangement with a manufacturer that works well for your skills and means. When looking for a program that's going to be a good fit for you, there are several things you should consider when making this determination: the product, the terms, your business plan and the company itself.

Network Marketing 

In network marketing, you agree to distribute products and services offered by a company, but you also work to recruit other distributors into the business as well. By establishing a network of distributors selling products, you are creating a residual income for yourself as you get the commission off of those sales. This type of business is also referred to as multilevel marketing. Make sure you thoroughly research any network marketing opportunity before you sign up to avoid any scams that are out ther. Investigate the reputation of the company, and scour the Internet for information about what its like to work with that company. As you research, beware of any network marketing opportunity that compensates more for bringing on new recruits rather than for actually selling its product or service.Some of the rising network marketing opportunities include Arbonne, Advocare and Forever Living.
