The vision of the INSPIRE Directive is that defined spatial data, metadata and services of various providers are consistent with the standardized specifications and accessible by a common location, i.e. a geoportal. The focus of this paper is on the establishment of a unified national metadata system that is INSPIRE compliant and combines metadata spatial data and the services of various providers. In Slovenia, formal responsible organizations must arrange and complete metadata and services using the SIST EN ISO 19115 metadata standard profile and other regulations and implementing rules determined by the INSPIRE Directive. The metadata systems of the Surveying and Mapping Authority of the Republic of Slovenia, the Slovenian official INSPIRE geoportal and the ARSO geoportal of the Slovenian Environment Agency are described. A comparison of them is then elaborated regarding the current state and compliance with the INSPIRE Directive. The spatial data and metadata system of the Swiss Federal Office of Topography swisstopo is also presented as an example of a remarkably comprehensive and significant solution.
