Description

Provides link to Open Access content for articles, when available. This is similar to the Unpaywall feature added in the 2019 November Primo release. Documentation explaining the differences between this customization and the Unpaywall feature can be found here:  Unpaywall in Alma, OADOI Customization in Primo (and Other Open Access)

In a full display record, checks for the presence of a DOI. Queries the OADOI API (v2), and upon the presence of an open access link, displays a bar with the link under the “View It” section.

Implementation Steps

1. In your local package, in the custom.js file, include the module ‘oadoi’ in your app definition. For example:
   
   var app = angular.module('viewCustom', ['oadoi']);
   
   If you are using other angular modules, include them in your app definition as well. For example:
   
   var app = angular.module('viewCustom', ['toggleInstitutions', 'oadoi']);
   
2. Also in the custom.js file, add the following  code within the anonymous function (that is, before the closing brackets at the end of the file):
   
   app.constant('oadoiOptions', {
  "imagePath": "custom/LCC/img/oa50_t.png",
  "email": "youremail@address"
})

angular.module('oadoi', []).component('prmFullViewServiceContainerAfter', {
  bindings: { parentCtrl: '<' },
  controller: function controller($scope, $http, $element, oadoiService, oadoiOptions) {
    this.$onInit = function () {
      $scope.oaDisplay = false; /* default hides template */
      $scope.imagePath = oadoiOptions.imagePath;
      var email = oadoiOptions.email;
      var section = $scope.$parent.$ctrl.service.scrollId;
      var obj = $scope.$ctrl.parentCtrl.item.pnx.addata;

      if (obj.hasOwnProperty("doi")) {
        var doi = obj.doi[0];
        if (doi && section == "getit_link1_0") {
          var url = "https://api.oadoi.org/v2/" + doi + "?email=" + email;
          var response = oadoiService.getOaiData(url).then(function (response) {
            var oalink = response.data.best_oa_location.url;
            if (oalink === null) {
              $scope.oaDisplay = false;
              $scope.oaClass = "ng-hide";
            } else {
              $scope.oalink = oalink;
              $scope.oaDisplay = true;
              $element.children().removeClass("ng-hide"); /* initially set by $scope.oaDisplay=false */
              $scope.oaClass = "ng-show";
            }
          });
        } else {
          $scope.oaDisplay = false;
        }
      } else {
        $scope.oaClass = "ng-hide";
      }
    };
  },
  template: '<div style="height:50px;background-color:white;padding:15px;" ng-show="{{oaDisplay}}" class="{{oaClass}}"><img src="{{imagePath}}" style="float:left;height:22px;width:22px;margin-right:10px"><p >Full text available via: <a href="{{oalink}}" target="_blank" style="font-weight:600;font-size:15px;color;#2c85d4;">Open Access</a></p></div>'
}).factory('oadoiService', ['$http', function ($http) {
  return {
    getOaiData: function getOaiData(url) {
      return $http({
        method: 'GET',
        url: url,
        cache: true
      });
    }
  };
}]).run(function ($http) {
  // Necessary for requests to succeed...not sure why
  $http.defaults.headers.common = { 'X-From-ExL-API-Gateway': undefined };
});
   
3. Be sure to edit the constant variables for the image path and email in this section of code.
   
   app.constant('oadoiOptions', {
  "imagePath": "custom/LCC/img/oa50_t.png",
  "email": "youremail@address"
})
   
   You can use any image you want or you could save and place the following image in your custom/YOURINSTITUTIONID/img/filename.png directory: oa50_t.png
   
   
   
4. Save the changes made to your custom.js file.
5. Zip and upload your package in the PBO.
6. Deploy your view.
