The democratisation of heritage through digital access is a well-documented aspiration. It has included innovative ways to manage interpretation, express heritage values, and create experiences through the ‘decoding’ of heritage. This decoding of heritage becomes democratised, more polyvocal than didactic exhibitions, and less dependent on experts. However, the decision of what ‘heritage’ is and what is commissioned for digitisation (the encoding) is not necessarily a part of this democratisation. This paper will consider how digitisation reinforces the Authorised Heritage Discourse through the lens of Stephen Lukes’ three (increasingly subtle) dimensions of power: conflict resolution, control of expression and shaping of preferences. All three dimensions have an impact on how public values are represented in heritage contexts, but the introduction of digitisation requires more resources, expertise and training within established professional discourse. Social media may have a positive impact on the first two dimensions, but can reinforce hegemony. Alternatives are subject to epistemic populism. The role of digitisation and social media in the democratisation of heritage needs to be better understood. Questions regarding the nature and process of digital interaction, in terms of whose heritage is accessible, affect the very issues of democratisation digitisation appears to promote.
