What are the benefits/drawbacks of SPARQL vis a vis SQL and XQuery?
SPARQL Protocol and Query Language: SPARQL Frequently Asked ...The jury is still out on best practices surrounding using SPARQL compared to other query languages. Some benefits of SPARQL include: Implicit join syntax. SPARQL queries RDF graphs, which consist of various triples expressing binary relations between resources, by specifying a subgraph with certain resources replaced by variables.
Related QuestionsWhat is SPARQL?
SPARQL Protocol and Query Language: SPARQL Frequently Asked ...SPARQL is a recursive acronym standing for SPARQL Protocol and RDF Query Language. As the name implies, SPARQL is a general term for both a protocol and a query language. Most uses of the SPARQL acronym refer to the RDF query language. In this usage, SPARQL is a syntactically-SQL-like language for querying RDF graphs via pattern matching. The language's features include basic conjunctive patterns, value filters, optional patterns, and pattern disjunction.

White LabsSome of the benefits of blending yeast strains would be to blend flavors or aromas of different strains. Over time one strain can dominate the other so the consistency of flavors would be lost over time. If flocculation is different between the strains, it is hard to collect an equal amount of each strain.

Internet Texoma FAQA Speed is the main reason that users are drawn to ISDN. Even with the slowest ISDN option, 64k, it is still faster than the fastest analog modems at 56k. Also, the speed is constant and does not fluctuate during a session. However, monthly rates for ISDN service are more expensive than normal POTS access, and there are additional cost features to consider.

Preservation Pennylvania :: About Us :: FAQThere may be both tangible and intangible benefits to owning property in a historic district. Some studies have shown that property values rise faster in designated historic districts than in similar, non-designated neighborhoods. This may be because owners have the assurance that their neighbors will be unable to make changes that would be detrimental to property values. In some localities, there are financial incentives for the rehabilitation of properties in historic districts.

Related QuestionsWhy not use SQL and/or XQuery to query RDF data? Why develop yet another query language?
W3C Semantic Web FAQSPARQL is a query language developed for the RDF data model; queries themselves look and act like RDF. I.e., the queries are independent of the physical representation of the RDF data (the structure of the databases, their representation in an RDF/XML file, etc). If query was done via, for example, XQuery, the application would have to know how that particular RDF data exactly represented as RDF/XML (and RDF/XML is only one of the possible serialization of the RDF data).
Related QuestionsWhat are the benefits/drawbacks of a freer flowing air filter?
Page not found - ThirdGen.orgFree flowing air filters such as K&N can provide a minimal increase in power (maybe 5 HP). The materials they're made of allow air to flow through much more freely than through stock paper air filters. The drawback to this is that more dirt can also pass through the air filter since the pores are usually bigger to allow for freer air flow. Some people have claims that the filters are great, while others think they only foul up performance due to the dirt they allow in.

Related QuestionsCan I use SPARQL to query RDFS entailments?
SPARQL Protocol and Query Language: SPARQL Frequently Asked ...It is sometimes desirable to use SPARQL to query triples entailed from subclass, subproperty, range, domain, and other relations which can be represented using RDF Schema. The SPARQL specification defines the results of queries based on RDF simple entailment. However, the specification does present a general, parametrized definition of graph pattern matching that can be expanded to other entailments beyond RDF simple entailment.
Related QuestionsCan I use SPARQL to query OWL entailments?
SPARQL Protocol and Query Language: SPARQL Frequently Asked ...For the most part, the answer to this question is the same as the above answer regarding RDFS entailment. However, OWL-DL axioms do not always result in a unique deductive closure, and as such querying OWL-DL entailments requires instantiating the parametrized SPARQL basic graph pattern definition with values appropriate for OWL-DL entailment. The open-source OWL-DL reasoner, Pellet, will answer SPARQL queries while considering OWL-DL entailments.
Related QuestionsWhat do blank nodes mean in a SPARQL query?
SPARQL Protocol and Query Language: SPARQL Frequently Asked ...For the most part, blank nodes in SPARQL queries function exactly as variables which cannot be returned to the user/client. So, the following two queries behave identically: SELECT ?title WHERE { _:book :hasTitle ?title } SELECT ?title WHERE { ?book :hasTitle ?title } However, a SPARQL query may not reuse the same blank node label twice in different basic graph patterns. That is, the following is not a legal SPARQL query: SELECT ?title WHERE { _:book rdfs:seeAlso ?g .
Related QuestionsCan I receive the results of SPARQL queries as RDF?
SPARQL Protocol and Query Language: SPARQL Frequently Asked ...The SPARQL protocol requires that the results of SPARQL CONSTRUCT and DESCRIBE queries be RDF graphs. SELECT and ASK queries, on the other hand, usually have their results returned as XML (or sometimes as JSON). However, as part of the group's test suite, the DAWG includes an RDF vocabulary which can be used to represent the results of SELECT or ASK queries in RDF.
Related QuestionsCan I receive the results of SPARQL queries as XML?
SPARQL Protocol and Query Language: SPARQL Frequently Asked ...The DAWG defines an XML serialization format, the SPARQL Query Results XML Format, which is used to return the results of SPARQL SELECT and ASK queries. The SPARQL protocol requires that the results of SPARQL CONSTRUCT and DESCRIBE queries be RDF graphs, which can be represented using the XML-based RDF/XML syntax.
Related QuestionsCan I receive the results of SPARQL queries as JSON?
SPARQL Protocol and Query Language: SPARQL Frequently Asked ...JSON is a lightweight serialization format which is a subset of JavaScript's literal-object notation. It is a useful format to use for SPARQL results when a Web client is issuing the queries and processing the results. The DAWG has published a Note defining a JSON format that closely follows the SPARQL Query Results XML Format, and which can be used to return the results of SPARQL SELECT and ASK queries. public-sparql-dev@w3.
