De Open Badges (OB2.1) specificatie is uitgebreidt met de volgende metadata-extensies die zijn geïmplementeerd in de dienst Edubadges.

}

 

Omdat wij een issuer niet zien als een losse entiteit, maar onder een onderwijsinstelling (Institution) plaatsen, hebben we ook metadataelementen nodig om deze institutions te identificeren. 
Het metadataveld InstitutionNameExtension wordt gebruikt om de instellingsnaam vast te leggen.

Voorbeeld: Erasmus Universiteit Rotterdam

Verwijzing (URL) naar de beoordelingstabel (grading table) van de instelling.
Grading tables: de hogeronderwijsinstellingen lichten de nationale cijfersystematiek toe voor meer transparantie en begrip. De toelichting bestaat uit grading tables die inzicht geven in verschillende cijferculturen in cohorten, programma’s en faculteiten binnen een instelling en in cijferculturen tussen instituten en landen.

Een uniek ID wat de instelling identificeert.

We gebruiken in Edubadges hiervoor het BRIN-nummer. 
De Basisregistratie Instellingen (BRIN) is een register dat door het Nederlandse Ministerie van OCW / DUO wordt uitgegeven en alle scholen en aanverwante instellingen bevat.

Voorbeeld: Instellingscode Hogeschool Rotterdam (Brin): 22OJ

Metadata extenties voor de badgeclass

      "ECTS": 2,5
   }
}


ECTS staat voor 'European Credit Transfer and Accumulation System'.
ECTS worden in Nederland uitgedrukt in studiepunten. Met studiepunten wordt aangegeven hoeveel tijd je kwijt bent aan een vak of opleiding. 1 ECTS staat voor 28 uur studeren.
Het begrip ECTS is afkomstig uit de Europese afspraak vanEuropese ministers van onderwijs die willen dat het hoger onderwijs van verschillende landen beter met elkaar te vergelijken is. Zo bevorderen ze de mobiliteit. Deze afspraken uit 1998 staan bekend als het Bolognaproces.

Minimale waarde: 0,5 ECTS. Maximale waarde: 240 ECTS

Voorbeeld: ECTS: 2,5

   }
}


Studiebelastingsuren
MBO instellingen gebruiken ipv studiepunten of ECTS het begrip 'Studiebelastingsuren' (SBU) om aan te geven hoeveel tijd je kwijt bent aan een vak of opleiding.

Voorbeeld: Studiebelastingsuren 24

{
  "@context": {
    "obi": "https://w3id.org/openbadges#",

   }
}


Tijdsinvestering in uren.
Waar de ECTSExtensie en StudyLoadExtensie gebruikt worden voor Edubadges die uitgegeven worden als onderdeel van een formeel curriculum, kan deze TimeInvestmentExtension metadata-extensie worden toegevoegd aan de badgeklasses voor extracurriculair onderwijs om de investering in uren aan te geven die de lerende moet investeren om deze Edubadge te kunnen verkrijgen.

Voorbeeld: TimeInvestment 36


{

EQF staat voor European Qualifications Framework.
Geeft informatie over het niveau van de cursus of opleiding volgens International Standard Classification of Education (ISCED).
In Nederland wordt dit uitgedrukt in NLQF.

The Open Badges (OB2.1) specification has been extended to include the following metadata extensions implemented in the Edubadges service.

   } 
}

 

Because we do consider an issuer as a separate legal entity, but place it under an educational institution, we also need metadata elements to identify these educational institutions. 
The metadata field InstitutionNameExtension is used to capture the institution name.

Example: Erasmus University Rotterdam
{
  "@context": {

}



Reference (URL) to the institution's grading table.
Grading tables: higher education institutions explain the national grading system for greater transparency and understanding. The explanation consists of grading tables that provide insight into different grading cultures in cohorts, programs and faculties within an institution and into grading cultures between institutions and countries.

A unique ID that identifies the institution. In the Netherlands we use the BRIN number in Edubadges for this purpose. 
The Basisregistratie Instellingen (BRIN) is a register issued by the Dutch Ministry of OCW / DUO that contains all schools and related institutions.

Example: Institution code Hogeschool Rotterdam (Brin): 22OJ

Metadata extentions for the badgeclass

   }
}


ECTS stands for "European Credit Transfer and Accumulation System. ECTS in the Netherlands are expressed in credits. With credits the amount of time you spend on a course is indicated.
1 ECTS stands for 28 hours of study.
The term ECTS comes from the European agreement of European ministers of education who want higher education from different countries to be more comparable. This is how they promote mobility. These 1998 agreements are also known as the Bologna Process.

Minimum value: 0.5 ECTS. Maximum value: 240 ECTS

Example: ECTS: 2.5

{

   }
}


Secondary Vocational institutions (MBO in the Netherlands), instead of credits or ECTS, use the term "Study Load Hours" (In Dutch: Studie Belasting Uren - SBU) to indicate how much time you spend on a subject or course.

Example: Study load hours: 24

   }
}


Time Investment in Hours. 
Whereas the ECTSExtension and StudyLoadExtension are used for Edubadges issued as part of a formal curriculum, this TimeInvestmentExtension metadata extension can be added to extracurricular education badge classes to indicate the investment in hours the learner must invest to obtain that Edubadge.
