                <p>Per map is vastgesteld welke handeling(en) uit bovengenoemde selectielijsten aan de vorming van de neerslag ten grondslag heeft gelegen.</p>
                <p>Bij de archiefvorming in het RIV zijn niet de handelingen het uitgangspunt geweest. Daarom kunnen in één map archiefbescheiden te vinden zijn die onder meerdere handelingen geplaatst kunnen worden. Eén en hetzelfde inventarisnummer kan dus op verschillende plekken in de toegang te vinden zijn.</p>
                <p>Indien het in een dergelijk geval handelingen betreft die alle met een V of alle met een B gewaardeerd zijn, vormt dit geen probleem.</p>
                <p>Als de bescheiden in één map betrekking hebben op zowel te bewaren handelingen als te vernietigen handelingen, prevaleert de waardering 'bewaren'. Deze map wordt dan in het geheel bewaard; de 'vervuiling' wordt op de koop toe genomen. Als de bescheiden in één map betrekking hebben op verschillende handelingen die allen met een V zijn gewaardeerd, maar waarbij verschillende vernietigingstermijnen zijn vastgesteld, wordt de langste termijn gehanteerd.</p>
                <p>Bij de bewerking is gebleken dat er neerslag te vinden is van handelingen die niet in het RIO/BSD zijn opgenomen. Hiervoor zijn nieuwe handelingen geformuleerd, te weten:</p>

                <p>Een handeling kan worden uitgevoerd door meerdere organisatieonderdelen van het RIV.</p>
                <p>Per handeling en per organisatieonderdeel zijn de dossieromschrijvingen ingevoerd. Onder dossieromschrijving wordt verstaan de omschrijving van de inhoud van een map zoals gehanteerd in de magazijnlijsten. De begrippen dossier en map zijn in de archieven van het RIV over het algemeen als identiek gehanteerd.</p>
