header Header. Can include these variables: - $channeltitle, $title: title of channel (channel.title)
- $channellink, $link: link of channel (channel.link)
- $channeldescription, $description: description (channel.description)
- $channeldate, $date: publication date of the channel (channel.pubDate)

Global HEADER setting
format Format of one item. Can include these variables:
- $title: news item title (item.title)
- $link: news item link (item.link)
- $description: news item description (item.description)
- $date: the publication date (item.pubDate, item.date)
- $category: the article category (item.category)
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>.

What matters more, the security of your warehousing facility or its productivity? Both matter equally, right?

Unfortunately, most business owners neglect basic warehouse security in favor of marginal profits. That is a mistake. An unexpected breakdown of a conveyor, a defective crane, a sudden robbery-all these scenarios can put everyday operations in disarray.

What’s more, disruptions such as these can result in order fulfillment delays or an increase in production hours. Further, they translate into lost deals and lost customers. What’s worse, though, is that they also represent hazards that endanger both the facility and its personnel.

Therefore, security procedures for your warehousing facility should be at the top of your priority list. Below, we've highlighted some measures to help you keep your warehouse secure and functioning at all times.


1. Commercial Fencing

Use commercial fencing to build security enclosures around items or areas that would otherwise remain exposed. Further, a commercial fence can keep personnel from wandering into sensitive or dangerous locations.

Today, business owners have unique options, such as Advanced Concrete Fence Forming Technology from AFTEC LLC. Fences with this type of technology are designed for versatility, safety, and efficiency. What’s more, their design is based on years of experience.

Additionally, they minimize handling, manufacturing, and installation labor. This leads to a reduction in turnaround time while ensuring a highly secure assembly process.



2. Pest Control

With multiple windows and big doors, a warehouse is an easy target for pests. Mice, rats, cockroaches, and other insects enter a warehousing facility in search of shelter and food. However, if neglected, they can infest your goods, destroy employees’ apparel, and even hamper daily production.

Therefore, it's important to conduct routine site inspections. Additionally, collaborate with pest control service providers for a healthy warehouse.

Also, use ultrasonic repellents to prevent insects from encroaching upon your facility in the first place. Finally, rearrange inventory periodically to make it challenging for vermin to get settled. That’s because pests shy away from environments where there is a lot of noise and activity.


3. Motion Detection

Motion detection technology is widely regarded as the backbone of advanced security systems. That’s because it is capable of recognizing if someone is on your premises.

Motion detection alerts the user when a sensor gets tripped by an individual's movement. This sends a signal to the security system's control panel.

In a warehousing facility, it can detect if someone who doesn't have authorized access is trying to sneak in. A reputable security system company will offer a central monitoring system that functions around the clock, every day of the week. This will ensure continuous safety of your warehouse.


4. Safety Amenities

Make modifications to your warehouse's design to ensure it's as safe as possible. Changes should involve safety amenities that keep both goods and personnel safe.

For instance, you can position bright lights throughout your space to offer clear vision whenever staffers are working. Further, install ergonomic equipment and workstations to minimize turning, bending, lifting, and other strained positions. This will reduce the risk of physical injuries.

Moreover, make the warehouse more accessible. Do this by working with architecture specialists to design separate lanes for pedestrians and forklifts. This will separate both forms of traffic, which is key to reducing falling loads and avoiding collisions.





Hopefully, these measures will help you get started as you move forward. Use them to identify ways to ensure optimal security in your warehousing facility.

Crowdsourcing. Have you heard of it? Many confuse this term with “crowdfunding,” but the two are not quite the same. To be clear, when crowdsourcing is used for generating funding, people generally refer to it as crowdfunding.

On the other hand, crowdsourcing in its purest sense refers to the process of going to a large group of people to get ideas or even to get work done, these days usually by way of the Internet. Often people in the crowd are willing to do the work for free, but that’s not always the case.

Crowdsourcing is a creative, organic dance of imagination and resourcefulness that has brought about numerous ingenious products, content, and ideas. In short, with crowdsourcing, you give your customers an opportunity to be interactive with your brand. In return, you get fresh new ideas for your business.




Below, we take a look at what crowdsourcing is all about.


A Brief History of Crowdsourcing

The first known example of crowdsourcing took place in 1714-long before the advent of the Internet-when the British government offered a monetary prize to whomever could come up with the best way to determine a ship’s longitudinal position.

A couple of hundred years later, in 1916, a 14-year-old boy won a logo-design contest when Planter Peanuts went to their customers for ideas. The boy’s design, the Mr. Peanut logo, still graces their products today.

In today’s world, open source software is a prime example of crowdsourcing at its best. Wikipedia, the popular online encyclopedia, is another case in point.

You could even argue that the igaming sector is another example of crowdsourcing, especially since gaming software developers seem to delight in using open-source Linux as a gaming platform. For just one example, take a look at the reputable and safe mFortune mobile casino app.



Use Crowdsourcing to Build Your Brand

Building a brand takes dedication, hard work, foresight, and a whole lot of patience. It is through trial and error, more often than not, that business owners attain great moments of breakthrough.

However, the lifeblood of any great brand is a free flow of great ideas. When those ideas are rolling, the business, too, is rolling. But when your free flow of ideas slows to a mere trickle, what’s an entrepreneur to do?

Let’s say you’re about to launch a new product but you’re fresh out of marketing ideas. You’ve been looking so closely at the development of your product that you can hardly see straight. As a matter of fact, you can barely remember why you thought your product was a good idea to begin with. And when you force yourself to think about marketing it, you just draw a blank. The same is true for your overworked, exhausted team.

This is where a crowdsourcing campaign can do your brand some good. For example, you could host a contest for the best ideas to include in your upcoming launch.


What Could Possibly Go Wrong?

When you go to your customers for ideas and free work, however, you’ll need to find a way to reward them somehow.

For example, the website Lego Ideas invites users to submit ideas for possible Lego sets. If the company decides to accept a user’s idea, he or she receives 1% of any commercial royalties.

But compensation doesn’t always have to come in the form of money. Often, some sincere acknowledgement from you will save the day. Additionally, you could toss in some name recognition on your site for their contributions to your endeavors.

Another drawback is that ideas from the crowd may need some cleaning up before they can be ready for public viewing. For example, when there are pranksters in the crowd, the results can be the precise opposite of what you had in mind, if admittedly hilarious.


Use Crowdsourcing to Get Your Business Unstuck

All the same, if you’re up against a wall in your business, consider going to the crowd. Ask your customers for advice. In other words, if you know you need some outside inspiration, crowdsourcing could open up a whole new world for you and your business.
