  As a result of the proliferation of 3D digitisation in the context of
cultural heritage projects, digital assets and digitisation processes - being
considered as proper research objects - must prioritise adherence to FAIR
principles. Existing standards and ontologies, such as CIDOC CRM, play a
crucial role in this regard, but they are often over-engineered for the need of
a particular application context, thus making their understanding and adoption
difficult. Application profiles of a given standard - defined as sets of
ontological entities drawn from one or more semantic artefacts for a particular
context or application - are usually proposed as tools for promoting
interoperability and reuse while being tied entirely to the particular
application context they refer to. In this paper, we present an adaptation and
application of an ontology development methodology, i.e. SAMOD, to guide the
creation of robust, semantically sound application profiles of large standard
models. Using an existing pilot study we have developed in a project dedicated
to leveraging virtual technologies to preserve and valorise cultural heritage,
we introduce an application profile named CHAD-AP, that we have developed
following our customised version of SAMOD. We reflect on the use of SAMOD and
similar ontology development methodologies for this purpose, highlighting its
strengths and current limitations, future developments, and possible adoption
in other similar projects.
