I would argue that that XML Schema is also Linked-Data-compatible as well as encompasing the notion of "record" in very precise terms. I regret that we didnt discuss this earlier. I can live with "application profile" as a rough notion, though.

I propose to continue linking mentions of "application profile" to the Singapore Framework -- SF is an explicitly Linked-Data-compatible notion of application profile (the only?), and the document starts by acknowledging that "profile" and "application profile" are used by other communities -- but to characterize "application profiles" in a very generic way. In the end, I pretty much stuck to the changes I proposed on Thursday, with some additional wordsmithing: -- http://www.w3.org/2005/Incubator/lld/wiki/index.php?title=Draft_Vocabularies_Datasets_Section2&diff=6007&oldid=6006 -- Reference to "application profiles" here left untouched (looks fine, Antoine!) -- Clarified wording in various ways (see diff). -- In addition to LLD XG and LOD-LAM, added DCMI and FOAF Project (citing their joint statement) to the list of advocates for alignments among element sets. Paragraph now reads: Alignments are likewise relevent for metadata element sets. As evidenced in the [http://labs.mondeca.com/dataset/lov/ Linked Open Vocabularies] inventory, practitioners generally follow the good practice of re-using existing element sets or building [http://dublincore.org/documents/singapore-framework/ application profiles] that re-use elements from multiple sets. Projects such as the [http://www.w3.org/2005/Incubator/lld/wiki/Library_Data_Resources#Vocabulary_mapping_framework Vocabulary Mapping Framework] aim at supporting alignment. The lack of institutional support for element sets can threaten the long-term persistence of their shared meanings. Moreover, some reference frameworks, notably FRBR, have been expressed differently in RDF, and these different expressions are not always explicitly aligned -- a situation which limits the semantic interoperability of datasets in which these RDF vocabularies are used. The community should facilitate the coordinated re-use or extension of existing element sets over the creation of new sets from scratch. Aligning already existing element sets when they overlap, typically using semantic relations from [http://www.w3.org/TR/rdf-schema/#ch_subclassof RDFS] and [http://www.w3.org/TR/2009/REC-owl2-primer-20091027/#Ontology_Management OWL], should also be encouraged. We hope that better communication between the creators and maintainers of these resources, as advocated by the [http://lod-lam.net/summit/ LOD-LAM initiative], the [http://dublincore.org/documents/dcmi-foaf/ Dublin Core Metadata Initiative and FOAF Project], and our own incubator group, will lead to more explicit conceptual connections among element sets. -- http://www.w3.org/2005/Incubator/lld/wiki/index.php?title=Draft_recommendations_page_take2&diff=6008&oldid=6005 Added: [http://dublincore.org/documents/singapore-framework/ Application profiles] provide a method for a community of practice to document and share patterns of using vocabularies and constraints for describing specific types of resources. -- http://www.w3.org/2005/Incubator/lld/wiki/index.php?title=Draft_Relevant_Technologies&diff=6011&oldid=5832 Added: http://dublincore.org/documents/singapore-framework/ Application profiles] provide a popular way to document how a community of practice defines a domain model and a pattern for re-using particular vocabularies with particular constraints in describing particular types of resources. In the latter, I share Jodi's concern about possible confusion between "alignment" and "ontology mapping", though not enough to propose it be re-worded on this point. However, the detail about versions of OWL and the inadequacies of RDFS seems a bit excessive here, so I have proposed a simplification: The current version of [http://www.w3.org/TR/owl-guide/ OWL Web Ontology Language], which provides methods for mapping equivalences across vocabularies ([http://www.w3.org/TR/2004/REC-owl-guide-20040210/#OntologyMapping ontology mapping]), allows experts to describe their domain using community idioms while remaining interoperable with related or more common idioms.
