Tiedonkeruumenetelmin\u00e4 toimivat tehdyt linkitysharjoitukset sek\u00e4 semistrukturoidut haastattelut domain-asiantuntijoiden ja dataintegraattorien kanssa. Haastattelut litteroitiin ja analysoitiin luokittelemalla keskeiset havainnot.\n\nP\u00e4\u00e4tuloksina todettiin, ett\u00e4 erityisesti domain-osaajan aikaisempi kokemus sek\u00e4 tietotekninen taitotaso vaikuttavat siihen, miten helposti valittavalla linkitysmenetelm\u00e4ll\u00e4 saadaan tuotettua m\u00e4\u00e4rittelydokumentti. Toisen tutkimuskysymyksen osalta vastaus ei ole yksiselitteinen. Linkitystaulukko on yleisesti helpommin l\u00e4hestytt\u00e4v\u00e4 ei-teknisen henkil\u00f6n toimesta, mik\u00e4li halutaan varmemmin tuotettua m\u00e4\u00e4rittelydokumentti dataintegraattorien k\u00e4ytett\u00e4v\u00e4ksi. RML-menetelm\u00e4n k\u00e4ytt\u00f6kokemusta voidaan parantaa yhteensopivilla k\u00e4ytt\u00f6liittym\u00e4editoreilla. Dataintegraattorit korostivat, ett\u00e4 paikallisen tason linkityksiss\u00e4 linkitysmenetelm\u00e4ll\u00e4 ei ole suurta merkityst\u00e4, vaan t\u00e4rkeint\u00e4 on iteraatio sidosryhmien v\u00e4lill\u00e4. Kolmannen tutkimuskysymyksen osalta todettiin, ett\u00e4 RML-menetelm\u00e4ll\u00e4 tuotettu m\u00e4\u00e4rittelydokumentti on helpommin tarkistettavissa syntaktisten virheiden varalta ja se mahdollistaa paremman hy\u00f6dynnett\u00e4vyyden erilaisissa graafitietokantojen avulla teht\u00e4viss\u00e4 linkityksiss\u00e4.
