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>.

Examples

  format="$t* [[$link][$title]]"

Business Owner's Guide To Vehicle Leasing

Leasing a vehicle through your business but still need to keep to a tight budget? It can be done! Leasing is a more cost effective way of getting your hands on a brand new car, truck or van without worrying about depreciation and big upfront costs.

Whether you're planning on leasing from here or just browsing for ideas, check out this helpful guide below to ensure you know how best to spend your hard earned cash:

 

leasing_keyChoose a vehicle that meets your needs

Of course that brand new model vanilla white van with leather and Bluetooth phone pairing would be really nice to have. Ask yourself these questins:

  1. Do I really need it?
  2. Will it cost more than the vehicle that actually meets my needs?

Sales men and be pushy so don't fall for their sales pitch if you don't have the budget for it. Do your beforehand, understand what your business needs and select your vehicle before you get to the lot.

 

How much mileage do you need?  

Mileage is tricky. Many of us drastically underestimate just how far we drive so it's important you overestimate when setting up your leasing policy. If you go over your agreed mileage amount you could be met with some unexpected fees that will be painful. Make a plan and know in advance what you think you will use and then over estimate for what you will REALLY use.

 

Keep the vehicle in good condition

It's important that you maintain your leased vehicle to a high standard to ensure you aren't charged for any maintenance when it's returned. Have it serviced every year, keep it clean inside and out, do not modify the car and try to avoid scratching or denting it - although that can be difficult. If there is damage to the vehicle, try to have this fixed professionally before returning it.

Ensure your maintenance costs are covered

Warranties and maintenance coverage is important when leasing a business vehicle. You don't want anything to go wrong a couple of months in and have to foot the bill. Ask your leasing company what maintenance is included and make sure you get what you need in terms of coverage.

 

For business owners, leasing a vehicle can definitely be a more cost effective way to go. It allows you to step into a higher end vehicle, for less money. Be sure you know what you need and have a plan and budget to stick to. As long as you take good care of the vehicle, service it regularly and get coverage for adequate maintenance and mileage, you should avoid any unexpected expenses down the road.

4 Simple Businesses You Can Run From Home

There are many compelling reasons to want to work from home. Perhaps you have small children at home or you can't stand office politics. Or, maybe you just cannot take the one hour commute to work every day - each way. Whatever your reason, I'm sure it's a good one. For me, I just like waking up a bit later, working in my pajamas if I want to and never listening to a boss I find to be a complete imbecile.

The good news is, as technology progresses, working from home (or telecommuting) is becoming much more accessible. Both self-employment and job opportunities are popping up everywhere; making it that much easier for you to work and/or make money from the comfort of home.

Here are few suggestions we have for you:

 

1. Open An Online Store:     

Online marketplaces such as Ebay and Amazon have made it very easy to set up a business selling goods online. You don't need a website or any expensive overhead. All you need is a product and a Selling account and you are in business.

If you need help selecting a product, check out sites like Alibaba where you can find almost any type of product imaginable. I recommend you sell what you like. For instance, if you are really into mountain biking and know a lot about quality bikes and gear, you could specialize in that. It really helps to enjoy what you sell so choose a product you really like or believe in.

While you won’t need to pay business rent or have expensive overhead costs (at least not at first), you will need to set up a home office for you to comfortably work in. I recommend you find some out-of-the-way place inside your home that is quiet. You will most likely need a desk, printer, phone and file cabinet to store your important work. As you begin to set up your office, you will find there are many online stationery suppliers  that have everything you need to set up the perfect home office – with a click of a button.

2. Become a Personal Tutor: 

If you have a talent, this can be a great business for you. Do you play an instrument, can you speak a different language, play the flute or or are you crazy good at math? If so, why not share your talent with others through tutoring and receive payment for all that knowledge you have. Tutoring is a huge industry and people can make a nice living doing what they know and love. All you need is your knowledge, some basic people skills and maybe some patience. List your business on Craigslist.com or find an agency to sign up with. Today, it is easier than ever to become a tutor for virtually no cost at all.

3. Become A Stock Trader: 

This one is not for the faint of heart as it certainly comes with a lot of risk. However, if you do have a love of the stock market, and the personality type to deal with the rise and fall of the stock market, perhaps trading could be for you. The invention of the internet and trading sites such as Trading 212, have certainly lowered the barriers to entry in this profession and made trading a profession that can easily be done from home.

Trading is a very flexible occupation and you can do it as little or as much as you like. It is important to remember that trading is not an easy occupation. It may take many months and perhaps thousands of dollars in courses to become good at it. You also have to do a lot of research on the companies you are interested in investing in – and the changes in the market can wipe out all of your investment if you are not careful.

4. Become A Child Care Provider:

Taking care of children for parents who need to work, shop, date, dine out and even travel has been a profession for centuries and is a great way to earn money from home. If you love children, then this may well be the perfect business opportunity for you. You can watch one child or open your business up to watching a few at a time. It’s up to you. Craigslist.com, local school’s, agencies and word of mouth are the best ways to get your message out there about our business. This is another great business you can start with little to no investment and if you love children, it is  a no brainers.
