Data Repository and Data Services
One of the chief objectives of the Phenoscape project is to present a centralized repository to store annotations entered by ichthyologists. These annotations can be queried from a user interface and used to answer Driving_Research_Questions and for Advanced Phenoscape_use_cases. The following tools which are under various stages of development, will serve to realize this objective.
Contents
Phenoscape Data loader
A data loader application to refresh the data in the Phenoscape database on a daily basis is under development. The application is being developed as a Perl module, which in sequential order:
- Downloads curated NeXML files from the Phenoscape SVN repositories
- Ichthyologists curate scientific publications using the Phenex character matrix annotator and these curations are stored in an SVN repository. The data loader downloads these data files on a daily basis for subsequent uploading into the relational database
- Drops and recreates the database
- Loads the requisite ontologies into the database
- The annotations of character matrices use terms that are defined in life science ontologies. These ontologies include the Teleost Taxonomy Ontology (TTO), the Relations Ontology, the Teleost Anatomy Ontology (TAO), and the Phenotype and Trait Ontology (PATO). The data loader loads all these definitions into the relational database
- Loads the data from the curated NeXML files into the database,
- The data loader transforms the curated data from NeXML syntax to a set of relational tuples (records), which are then sequentially inserted into the database
- Invokes the OBD reasoner to elicit implicit information from the data and adds them to the database
- The OBD reasoner uses definitions of transitive relations, relation hierarchies, and relation compositions to infer implicit information. These inferences are added to the relational database in the final step
- Logs incomplete annotations into a log file
- The data loader does not load incomplete annotations from the NeXML files into the database. Incomplete annotations contain null values for taxa or phenotype or both. Instead, it logs these incomplete annotations on a file-specific basis in this Problem Log Format. Curators can then work on finishing these annotations which will be subsequently loaded into the database in the next execution of the data loader.

Web services
Each service may support multiple media types. The desired media type can be specified by appending ?media=json or similar to the request URL. URI specifications are defined (loosely) using URI Templates.

Error
If there is no term with the given ID, the service should return "404 Not Found".
Handling of anonymous post-compositions
Autocomplete
URI
<BASE URI>/term/search?text=[input]&name=[true|false]&syn=[true|false]&def=[true|false]&ontology=[ont1,ont2,...]
All URI parameters are optional except for text. Default values are name=true, syn=false, def=false. The "ontology" parameter should be a comma-separated list of ontology prefixes to search within. If not given, the default is to search all ontologies. Specifying "ZFIN" for the ontology should be a search for gene nodes, by gene name.
Returns
JSON: <javascript> {
"matches" : [
{ // overall format
"id" : "TAO:0001514",
"name" : "bone",
"match_type" : "name" | "syn" | "def",

Error
If there are no terms matching the given input, a document should still be returned, containing an empty results list.
Anatomy search summary
URI
<BASE URI>/phenotypes/summary/anatomy/{term_id}
term_id is an anatomy search term. This service returns a summary of all the phenotype annotations involving that anatomy term (or its descendants, via reasoning). The summary is grouped by quality attribute term - all annotations with qualities descending from the same closest attribute should be grouped into the same count.
Returns
JSON: <javascript> {
"term" : { "id" : "TAO:xxxxx", "name" : "some anatomical part"},
"qualities" : [
{
"id" : "PATO:000xxxxx",
"name" : "shape",
"taxon_annotations" : {
"annotation_count": 5,
"taxon_count" : 3
},
"genotype_annotations" : {
"annotation_count" : 3,
"genotype_count" : 2
}
},
{
// another quality attribute
} // etc.
]
} </javascript>
Anatomy taxon annotations results
URI
<BASE URI>/phenotypes/anatomy/{anatomy_term_id}/taxa/{quality_term_id}?attribute=[true|false]
anatomy_term_id is an anatomy search term. This service returns all of the phenotype annotations involving that anatomy term (or its descendants, via reasoning) and the given quality term (or its descendants, via reasoning). In the result, the values of the outer "entity" and "quality" keys are the search inputs.
The "attribute" query parameter is optional - if "true", the service should first find the corresponding attribute for the given quality, and use that in the search instead of the given quality. The default should be "false".
Returns
JSON: <javascript> {
"entity" : { "id" : "TAO:34242", "name" : "some anatomical part" },
"quality" : { "id" : "PATO:1234", "name" : "some attribute quality"},

Anatomy genotypes annotations results
URI
<BASE URI>/phenotypes/anatomy/{anatomy_term_id}/genes/{quality_term_id}
anatomy_term_id is an anatomy search term. This service returns all of the phenotype annotations involving that anatomy term (or its descendants, via reasoning) and the given quality term (or its descendants, via reasoning). In the result, the values of the outer "entity" and "quality" keys are the search inputs. The genotype annotations are grouped together by gene. If the genotype is not linked to a specific gene, it should be put in the "other_genotype_annotations" group at the top level.
The "attribute" query parameter is optional - if "true", the service should first find the corresponding attribute for the given quality, and use that in the search instead of the given quality. The default should be "false".
