FOAF (an acronym of Friend of a friend) is a machine-readable ontology describing persons, their activities and their relations to other people and objects. Anyone can use FOAF to describe him or herself. FOAF allows groups of people to describe social networks without the need for a centralised database (via Wikipedia).

Foafpress is an open source PHP web application and presentation engine for RDF data stored in files.

It makes aggregating and publishing data from multiple web sources via Linked Data possible.

The application can read RDFXML, Turtle + N-Triple files and supports automatic content negotiation, currently for RDFXML, Turtle, N-Triple, HTML and RSS.

There are ready-to-use templates and controllers for foaf:Person and foaf:Group.

It can create a merged activity stream from Atom/RSS feed resources, render Twitter and Identi.ca statuses including @account, URLs and #hashtag links and has icons for ~35 social websites (like Twitter, Youtube, Facebook).

Info: This is a review of a paid application.

Avactis, the powerful e-commerce application for any-sized business (which was previously shared at WRD), has recently released an exciting feature for integrating the stores into Facebook.

Considering the size of Facebook, the amount of time user's spend in the website and how fast a word can spread with it, it is definitely a huge market.

By simply creating a Facebook page, adding the Facebook Avactis application and installing the Avactis Storefront extension, the page gets a store tab which displays your complete store inside Facebook with a theme that integrates to it completely.

After setting up the store, visitors can:

• browse categories
• view product details
• enter promo codes
• enter gift certificates
• add products to shopping cart

right inside Facebook and will be forwarded to the original store during the checkout process.

The best part is, it is only a one-time-setup, the rest is handled automatically and you just need to maintain the main web store.

New Editions of Avactis

Avactis has also launched new 2 new editions of their e-commerce platform; Lite and Premium.

Lite Edition:

It is a package for web designers/developers and hosting providers who provide e-commerce related services to their clients.

The package has all the core features of the software but doesn't include support credits and comes with a much cheaper price.

Premium Edition:

This is the complete package which has all the features including installation and Facebook integration. Also, it includes 1 month of Level-1 support and extra support credits.

P.S. Both editions are hosted on user's server for unlimited time without any restrictions.

We have all seen applications that enable us to find the song name or the artist by simply playing a small part of that song.

Echoprint is an open source resource that makes this possible and easy-to-integrate into any website/application.

It is a music identification system which listens to music signals, compares them with the ones in its database (of 150,000+ items) and tells you what song is playing.

The system has 3 parts:

• code generator which converts the audio data into a unique code
• server (Apache-based) which responds to the queries made with the generated code
• data which includes hashes of 150,000+ songs

You can choose to run your own server or Echoprint already hosts one where you can send queries to (using code generator is still needed).

P.S. There is also an Echonest PHP API for easily reaching the datastored.

PCSS is a PHP(5) library that allows us to write CSS(3) code with a simpler + shorter syntax and brings awesome features like server-side browser specifics, class nesting, default unit and variables.

As the CSS is preprocessed on the server-side, every designer's dream: "dynamic CSS" comes true and variables can be used easily.

The rules being processed on the server-side also helps avoiding redundant commands (like many "-webkit", "-moz", etc.) as only the rules needed for the browser will be generated.

Using the library, we can set a default image directory and default unit (em or px) to prevent rewriting them again and again.

There are also shortcuts provided for @font-face usage and nesting of CSS rules.

Today, videos are a significantly large part of the internet content. Not only websites like Youtube or Vimeo but services like Netflix or Hulu and much more support this rise.

Videola, an open source video management and delivery platform built on Drupal, can easily help creating a video-based website with users and even e-commerce being a part of it.

Subscription plans can be created and videos can -optionally- be streamed only to subscribed users, they can add/remove videos to the queue (like Netflix) and video analytics per subscriber can be viewed.

It is possible to show preview-images/videos to non-subscribed users and there is support for in streams advertising + branding bumpers.

For quicker access to the content, there are widgets like "similar videos" or "popular videos". Also, items can be tagged + categorized.

And, besides desktop browsers, videos can be watched in iOS and Android.

Building good-looking HTML forms which work well in every browser and applying client+server-side validation usually takes a serious development time.

Zebra_Form, a free PHP library, handles this process very well and enables us to create secure and chic forms with a few lines of PHP code.

The output can be generated either with the ready-to-use styles (with valid HTML) or with any new/custom ones.

An integrated cross-site scripting prevention mechanism removes any possible malicious code submitted. It also helps preventing automated spam submissions.

The client-side validation is handled with jQuery, alerts are displayed inside tooltips and many validation types can be used (like "required, e-mail, length, etc.").

Besides standard input types, Zebra_Form supports Ajax-like file uploads, date-time pickers and captchas.

Today's internet user interacts with others using many different services like Facebook, Twitter, blogs, etc.

Friendika, an open source PHP/MySQL application, integrates with such services and allows you to control your social networking stream from a single interface.

The supported services include Facebook, Twitter, WordPress, Blogger, Identi.ca, RSS feeds, e-mail integration and more.

Friendika is actually much more than that, it is a distributed social-network which doesn't require any 3rd party services and has its own Facebook-like features including, status updates, photo sharing/tagging, like/dislike, creating groups/fan pages or location sharing/geotagging.

And, the best part is; every Friendika user can connect with any other Friendika user on any installation without limits.
