Claude There is the ParameterizedSparqlString functionality which is essentially just textual parameterization - https://jena.apache.org/documentation/query/parameterized-sparql-strings.ht ml - so it is somewhat limited but that has existed in ARQ for a year or two now.
There was some talk about doing the parameterisation at the query/algebra level. Certainly some of the plumbing that supports parameterisation at the algebra level already exists because it is used by optimisations Maybe you could elaborate more on what you intend?
