As information technologies gains common adoption in the humanities, cultural heritage study remains a special domain. Fundamentally interdisciplinary, cultural heritage works articulate several specific challenges: incompleteness, close link to documentation and the need for many domain collaborating. Modeling tools and methods have been under vibrant development in the past twenty years. But while a lot of e↵orts has been put towards overcoming practical issues, ethical and methodological issues nowadays require further advances. The Reseed project aims to bridge some gaps in the digital use for cultural heritage. This paper aims to shed light on the need to embrace heterogeneity with the aim to entrench model contextualized analysis. Currently in the process of developing fitting solutions, we present our partial implementation, which we supplement with more global requirement specifications. We base our proposal on a domain analysis and confine its scope within a critical discussion. Loïc Jeanson LS2N
