Community:Main
From Odp
This area is dedicated to discussing modeling issues, i.e a questions or problems that arises during the ontology engineering process.
- Tell me more about modeling issues
- A list of modeling issues is displayed in the table below
- If you want help in solving a modeling issue you may Post a modeling issue now.
- Each issue has a discussion page for jointly solving the issue.
- If you see an issue below you can click on it and contribute input towards a solution.
- If you would like to add an important issue along with its solution, you may Post a modeling issue now.
- Ideally, all posted modeling issues will evolve into at least one well-defined problem that is linked to a specific ontology pattern that solves it.
Help on posting modeling issues.
Why not just use discussion lists?
| Before posting your modeling issue look at the list below, maybe somebody else had a similar problem |

| Data production | I would need to describe the following pattern:
"A device/sensor/software application produces a piece of data (e.g., a measure for a sensor, a computation for an application). More generally, how to describe the information producer/consumer model? |

| Different types of relationships | The flexibility of the ontology editor to represent taxonomies based on different types of relationships between concepts and with specific features, constraints and rules for each type of relationship. E.g., specialization (is-a) taxonomies, composition (part-whole) taxonomies, lists, etc. The reason is that some features for the specialization taxonomies (represented by the existing editors, e.g., the property inheritance) are not always appropriate for taxonomies based on other types of relationships. Also, the editor flexibility to represent taxonomies based on new types of relationships and specific features. | Ontology | AlexandraGalatescu | |

| Faceted Classification Scheme | This modeling issue refers to the conceptualization of a specific domain concept using a Faceted Classification Scheme (FCS).
A FCS is defined as: "a set of mutually exclusive and jointly exhaustive categories, each made by isolating one perspective on the items (a facet), that combine to completely describe all the objects in question, and which users can use, by searching and browsing, to find what they need" (Denton, 2003). The section Diagram below presents an example of a FCS in the domain of "Dishwashing Detergent" from (Denton, 2003). |

| Ontology-based models | Patterns for building ontology-based models for applications, by inter-ontology relationships, constraints and rules. General patterns for inference and search on ontology-based models. | Ontology-based modeling | AlexandraGalatescu | |
| Overloading OWL sameAs | General Issue: owl:sameAs is being used in the linked data community in a way that is inconsistent with its semantics. | General | MichaelUschold | |
| PharmaceuticalProducts Composition | The pharmaceutical products or drugs are chemical products composed by a set of ingredients (substances).
The ingredients are substances in a concrete dosage. The ingredients are divided in one main ingredient (mainly an active ingredient) and a set of excipients (other substances) The drugs are uniques based on their concrete composition. I checked the Parts and Collections patterns, but I'm not pretty sure to use the Composition or Constituency in this case |

| SnomedCTToOWL | In the context of the Semantic Nomenclature case study, we need to extract a light ontology module from Snomed CT and convert it to OWL. We need on the one hand to use the Snomed CT classes for modeling the pharmaceutical clinical product and the dosage, plus some classes around. We plan to take a small set of instances of Snomed for experimentation. This will be the first step in order to map the resulting ontology to the Semantic Nomenclature ontology network. The focus is on semantic interoperability among different pharma terminologies. | Pharmaceutical | TomasPariente | |
