+### Ontology-Verifier
+A RDF Ontology verifier and ontology trouble shooter for CASE/UCO.
+
+### What it does
+Ontology-Verifier takes output of a tool (JSON/JSON-LD/XML/etc...)
+and attempts to verify it aligns with a RDF based ontology (OWL/N3/ttl).
+Any entry in the tool's output that is NOT in the Ontology (specified via CLI)
+will display an error. CLI arugments can be added to cause a debugger to start
+so you may explore the graph to view where things went wrong.
+
+
+### How it works
+Verifier.py will read in an RDF vocabulary defined via ``` -g``` (glossary) to
+check a custom tool's output against via ```-i```. The Python library rdflib 
+is used to turn the RDF schema into tripples which are then broken into three lists; 
+subject, predicate and object. Finally, each element of the tools ouput within
+the tool's subject and predicate are checked againast the glossary's subject 
+and predicate to confirm the existence of these RDF elements. If an element is 
+found or not found it is displayed to the user. BNodes are skipped  as they
+have no appropriate label in RDF and should not be used to verify an ontology.
+
+
+#### Why not SPARQL?
+In order to facilitate a broad range of ontologies and custom tool outputs,
+SPARQL queries are not used for verification. CASE/UCO allow for robust
+flexibility and this tool  aims to compliment this approach.
+
+
+### Installation
+```
+sudo pip install -r requirements.txt 
+```
+
+### Unit Tests
+The ontology verifier is heavily reliant on 3rd pary libraries, primarily RDFlib.
+RDFLib is under heavy development. To ensure compatability with new releases
+unit tests have been written to check for consistency.
+
+#### Run Unit Tests
+```
+cd tests;
+python test_verifier.py;
+```
+
+### Usage
+
+#### CLI Usage
+* ``` -g ```: Define the RDF schema (aka glossary) in use for your ontology.
+* ``` -gf ```: Define the format the schema is in. By default verifier
+will try to auto-guess based on extension. However, if additional plugins are
+installed it is best practice to manually specify it.
+
+* ``` -i ```: The external tool's output you want to verify the ontology 
+against.
+
+* ```-if```: Define RDF schema for tool data that's being injested.
+* ```--debug```: Break on errors that occur within ```--verify```.
+* ```-tg```: Print subject, predicate, object for each graph within tool schema.
+* ```-gg```: Print subject, predicate, object for each graph within glossary schema.
+
+
+#### CLI Example
+
+
+* Check for inconsistencies between graphs:
+
+```
+verify.py -g case.ttl -gf turtle -i output.json-ld -if json-ld --verify=1
+```
+
+* Check for inconsistencies between graphs with color output:
+```
+verify.py -g case.ttl -gf turtle -i output.json-ld -if json-ld --verify=1 --color=1
+```
+
+* Enter debug mode. This will cause a PDB session to open when an inconsistency is met. This can be useful for manually navigating the RDF graph in Python.:
+```
+verify.py -g case.ttl -gf turtle -i output.json-ld -if json-ld --verify=1 --debug=1
+
+```
+
+* Print all graphs for tool's schema.
+
+```
+verify.py -g case.ttl -gf turtle -i output.json-ld -if json-ld -tg=1
+
+```
+
+* Print all graphs for ontology's schema.
+
+```
+verify.py -g case.ttl -gf turtle -i output.json-ld -if json-ld -gg=1
+
+```
+
+### Submitting an Issue
+If/when you run into an issue with a given RDF schema format or the verifier.py script, please open an issue with the error
+and as much technical detail as you can provide.
