The role of technology for enhancing trialogical practices has been framed in the KP-Lab project by four types of mediation which have specified the general aims of the technology development. They have given general categories for grouping high level requirements developed in relation to pedagogical cases. These types of mediation are reformulations of the ones introduced by Rabardel and Bourmaud (2003; see Hakkarainen 2008), i.e., epistemic, pragmatic, collaborative, and reflective mediation, or multimediation.

Epistemic mediation: Creating and working with knowledge artefacts. The aim is to give support for users to create, transform and organize shared knowledge artefacts, to support commenting on shared artefacts (object-bound commenting and chat), and development of shared artefacts (drafting and versioning iteratively), as well as sustained use of knowledge artefacts and conceptualizations.

Pragmatic mediation: Organizing and coordinating knowledge-creation processes. The aim is to provide flexible possibilities and support for planning work processes, support for updating and revising the plans, as well as coordinating the collaborative knowledge processes with other practices.

Collaborative mediation: Building and managing networked communities and social relations required for carrying out knowledge-advancement efforts. The aim is to support networking, community building and interaction around shared processes and artefacts as well as interaction across different groups and communities allowing users to lean, learn, share and combine on each others' competencies, expertise and experience.

Reflective mediation: Making visible, reflecting on, and transforming knowledge practices. The aim is to enable users to reflect on their practices (processes), and jointly analyze and developed the practices and processes.

The KP-Lab system and KPE is designed to support multimediation by providing a shared knowledge space that facilitates all four modes of mediation and their flexible use.
