What Are Frames?

Java objects stored in graphs

Interfacecentric

Annotation based

VertexFrame: LikeableVertexFrame: LikerEdgeFrame: Likes

Example 1 – Simple Social Graph

VertexFrame: Replica extends Likeablereplicaid, title

VertexFrame: Databaseserver, filepath

EdgeFrame: InstanceOf Replica <-> Database

VertexFrame: Viewtitle, isCalendar

EdgeFrame: FoundIn Replica <-> View

EdgeFrame: IndexedIn Database <-> View isBuilt

Example 2 – Red Pill Now Forensics

VertexFrame: PersonfirstName, lastName

VertexFrame: Organizationname, website

EdgeFrame: WorksAt Person <-> Organizationtitle, startDate, endDate
