As such, please do NOT make data contributions to this repository. Contribute any new academic domain names to the Ruby version of this package at . Please follow the [contribution guidelines](https://github.com/leereilly/swot/blob/master/CONTRIBUTING.md) noted on Lee's repository. I will be pulling changes to upstream domain data. > If you have a product or service and offer **academic discounts**, there's a good chance there's some manual component to the approval process. Perhaps `.edu` email addresses are automatically approved because, for the most part at least, they're associated with American post-secondary educational institutions. Perhaps `.ac.uk` email addresses are automatically approved because they're guaranteed to belong to British universities and colleges. Unfortunately, not every country has an education-specific TLD (Top Level Domain) and plenty of schools use `.com`or `.net`. > Swot is a community-driven or crowdsourced library for verifying that domain names and email addresses are tied to a legitimate university of college - more specifically, an academic institution providing higher education in tertiary, quaternary or any other kind of post-secondary education in any country in the world. ### Installation [](#installation) Install through Composer. ``` "require": { "stormcode/swotphp": "1.0" } ``` ### Usage [](#usage) The easiest way to get started with SwotPHP is to use a facade to access functionality. However, the base implementation is present as a plain ol' PHP object in case developers want control over the construction themselves. The implementation has an injected dependency on [PHP Domain Parser](https://github.com/jeremykendall/php-domain-parser), an implementation of a URL parser backed by the [Public Suffix List](http://publicsuffix.org). Framework-specific facades / service providers may be added later. The native facade is a good example of how the object should be instantiated. **Native** ``` require_once('vendor/autoload.php'); use SwotPHP\Facades\Native\Swot; ``` #### Verify Email Addresses [](#verify-email-addresses) ``` Swot::isAcademic('lreilly@stanford.edu') # true Swot::isAcademic('lreilly@strath.ac.uk') # true Swot::isAcademic('lreilly@soft-eng.strath.ac.uk') # true Swot::isAcademic('pedro@ugr.es') # true Swot::isAcademic('lee@uottawa.ca') # true Swot::isAcademic('lee@leerilly.net') # false ``` #### Verify Domain Names [](#verify-domain-names) ``` Swot::isAcademic('harvard.edu') # true Swot::isAcademic('www.harvard.edu') # true Swot::isAcademic('http://www.harvard.edu') # true Swot::isAcademic('http://www.github.com') # false Swot::isAcademic('http://www.rangers.co.uk') # false ``` #### Find School Names [](#find-school-names) ``` Swot::schoolName('lreilly@cs.strath.ac.uk') -> "University of Strathclyde" Swot::schoolName('http://www.stanford.edu') -> "Stanford University" ``` ### Known Issues [](#known-issues) - Lack of automated data import from Ruby gem's domain list. - There are architectural issues with the package resultant from differences in PHP and Ruby-isms. When I get time, there are two areas I'd like to focus on: 1. Consolidate some of how the internal API flows while maintaining public interface. 2. Implement a different mode of accessing the public suffix registry. Currently, the package is possibly abusing an excellent [URL parser](https://github.com/jeremykendall/php-domain-parser) and I'd like to investigate the possibility of a separate component dedicated to modeling the Public Suffix registry's ruleset and algorithms. ### Health Score 39 — LowBetter than 86% of packages Maintenance51 Moderate activity, may be stable Popularity26 Limited adoption so far Community11 Small or concentrated contributor base Maturity57 Maturing project, gaining track record Bus Factor2 2 contributors hold 50%+ of commits How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
