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. Note that some of the variables are already used above. This is done by purpose to use different feeds with the same formatting parameters. If there's a conflict the non-dc tags have higher precedence, i.e. a <title> content </title> is preferred 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 referring to the <content:encoding> content </content:encoding>.

5 Profitable Businesses You Could Start Today with Little Money

Jumping from the daily 9-5 routine of working for someone else to becoming your own boss can seem like an all-too-distant dream. Nonetheless, ideas for profitable businesses you might want to start float through your mind day and night.

However, you fear that there simply isn’t a sufficiently strong market for the business idea that most appeals to you. Or you might be afraid that most businesses would require you to spend money you currently lack.

But wait. You could actually be mistaken on both counts. Here are some ideas for exciting and profitable businesses that would require only a modest financial outlay.




Developing Mobile Apps

We use our smartphones for a huge range of activities these days. Listening to music, shopping, keeping in touch with friends…. The list goes on. It shouldn’t surprise us, then, that the mobile app market is booming. As a matter of fact, Startups.co.ukreports thatit generated about $37bn in revenue in 2017.

You could develop a mobile app-and at pleasantly little financial expense. However, before you proceed, carefully consider what functionality and target audience your app will have.


Selling Creative Work

There are various creative fields in which selling your creative work-even to a global market-can be delightfully simple. Those fields include photography, art, music and literature.

You would also have flexibility over how you sell the work. You could easily upload your music, for example, to an online shop. Then you could sell it as downloads.

On the other hand, if you like working on art, you might already have many pieces of art. You could create an online store where customers could view your work and place orders. Or, you could take advantage of the opportunity afforded by a site such as Etsy. Then you could simply mail the pieces to customers when they purchase them.


Teaching Online Courses

If you have already built up a formidable body of knowledge about a particular subject, you could teach that knowledge to other people through providing online courses.

When going down this route, however, you might need to spend a lot of time creating the courses. Then you would need to set up your website before you could start selling anything. All the same, your cash outlay should be pretty light.

Furthermore, once your site has started making money, some occasional marketing efforts would be all you would need to put forth in order to keep that income steady.



If you are the kind of person who can effortlessly absorb numbers in a way that amazes your friends, you might be an awesome bookkeeper in the making!

You can take your training through online courses. Your aim should be to get certified with a professional body. For instance, that body in the UK is the Association of Accounting Technicians. Training for that certification will cost you only about 40. Your local community will have many small businesses that could benefit from your bookkeeping, says Money Nuggets.



Being a Lifestyle Coach

All of us can easily lose our way in our efforts to thrive. However, you might be able to help others get back on track by becoming a lifestyle coach.

Whether you will be assisting people with their relationships, their careers, their personal development or something else, don’t overlook insurance concerns. For example, you could compare multi bike insurance if you will often be traveling to provide your coaching services widely. This is important, because you would be legally barred from driving a motorbike on UK roads if you lack the right insurance.


Get Started Today

So if what you really want to do with your life is start your own business, don’t wait. Take the first steps today and be on your way!

How to Start a Private and Lucrative Recycling Business

Starting a recycling business is a responsible environmental decision. What’s more, it’s an opportunity to earn a good living.

One of the biggest things that prevents people from doing it is the misconception that these businesses focus only on collecting old paper, bottles, and soda cans. In reality, though, the biggest profit comes from removing gold from cell phones and computers as well as refurbishing and selling household goods.




Skills Needed to Start a Recycling Business

People who enjoy the most success in this kind of business understand where to find items to recycle. They also know the best markets to resell them. What’s more, they know and use terms associated with the business that describe it as a process. Some of these terms include:

  • Reclaim
  • Recover
  • Reprocess
  • Reuse

Households across the country generate approximately $1 trillion worth of waste every year. However, recycling a large portion of that waste results in the need to use less energy and fewer natural resources. Additionally, with each generation becoming more environmentally conscious than the last, there has never been a better time to start a recycling business.


Decide Who to Serve

Both individual neighborhoods and businesses need the services of a recycling business. The first thing for the new business owner to decide is the customer base that he or she wants to serve. For example, it could be private residences, government agencies, or public schools. It's also a good idea to choose a niche industry, such as metal, electronics, tires, or construction waste.


Legal Matters

It's advantageous for the new business owner to meet with an attorney and decide on a business structure. Further, it’s a good idea to file for copyright protection on the business name. The business lawyer can also advise whether to start the business from scratch or buy a franchise. Another person to meet with is a business insurance agent to decide on coverage.

Finally, obtaining certification in one or more areas related to health, safety, and recycling helps the new business owner distinguish himself or herself from the competition.


State and Small Business Grants to Start a Recycling Business

Before starting this kind of business, entrepreneurs should check with the Department of Environmental Protection or the conservation agency for their state. The most likely place to find funding with these agencies is through a business development grant. Some state grants restrict eligibility to new recycling businesses employing a limited number of people. Other states offer matching grants, which means the state will contribute the same amount as the new business owner.

The United States Environmental Protection Agency offers grants for new recycling businesses through a program it sponsors called the Small Business Innovative Research Program. Another idea is to apply for a federal grant.



Help to Educate the Public on Recycling

Americans throw away millions of pounds of items every year that could have been recycled. An important function of any recycling company is to provide education about recycling and then offer to pick up the items. The most common categories of recyclable items that end up in landfills include:

  • Appliances
  • Batteries
  • Carpet
  • Clothing
  • Cosmetics
  • Compact fluorescent light bulbs
  • Computers and electronics
  • Crayons
  • Eyeglasses
  • Oil

Seeing these and other items get used again instead of polluting the earth in landfills makes recycling a personally rewarding career as well as a financially rewarding one.
