SimpleGraph
SimpleGraph is an open source project that allows to wrap Systems APIs in a way that graph algorithms and storage can be applied. As an implementation Apache Tinkerpop/Gremlin is used.
Modules
| SimpleGraphModule | name | logo | url | documentation |
|---|---|---|---|---|
| SimpleGraph-CalDAV | CalDAV |  | https://en.wikipedia.org/wiki/CalDAV | makes Calendar data available via ical4j |
| SimpleGraph-CardDAV | CardDAV |  | https://en.wikipedia.org/wiki/CardDAV | makes VCard data available |
| SimpleGraph-Excel | Excel |  | https://en.wikipedia.org/wiki/Microsoft Excel | makes Microsoft Excel workbooks accessible via the Apache POI API |
| SimpleGraph-FileSystem | FileSystem |  | https://en.wikipedia.org/wiki/File system | makes your FileSystem accessible via the Java FileSystem API |
| SimpleGraph-GeoJSON | GeoJSON |  | https://en.wikipedia.org/wiki/GeoJSON | makes GeoJSON data available |
| SimpleGraph-github | GitHub |  | https://github.com | makes GitHub content accessible to Graph processing. |
| SimpleGraph-HTML | HTML |  | https://en.wikipedia.org/wiki/HTML | makes HTML files accessible via HTML Cleaner parser |
| SimpleGraph-JSON | JSON |  | https://en.wikipedia.org/wiki/JavaScript Object Notation | makes JSON parse results accessible to Graph processing. |
| SimpleGraph-Java | Java |  | https://en.wikipedia.org/wiki/Java (programming language) | makes Java code parse results accessible to Graph processing. |
| SimpleGraph-Mail |  | https://en.wikipedia.org/wiki/MIME | makes Mail data available via Apache Mime4J | |
| SimpleGraph-MapSystem | MapSystem |  | https://en.wikipedia.org/wiki/Hash table | supplies a simple wrapper for a graph with nodes that have key/value pairs in form of HashMaps. We would not really need this since Apache Tinkerpop/Gremlin already supplies us with properties per node/vertex. Still this system is useful as a helper system and to illustrate the wrapping concepts and possibilities of SimpleGraph |
| SimpleGraph-MediaWiki | MediaWiki |  | https://www.mediawiki.org/wiki/API:Main page MediaWiki | makes MediaWiki site content accessible to Graph processing. It exposes the MediaWiki API using the mediawiki-japi Library by BITPlan. |
| SimpleGraph-PDF |  | https://de.wikipedia.org/wiki/Portable Document Format | makes Portable Document Format (PDF) files accessible via the Apache PDFBox® API | |
| SimpleGraph-PowerPoint | PowerPoint |  | https://en.wikipedia.org/wiki/Microsoft PowerPoint | makes Microsoft PowerPoint presentations accessible via the Apache POI API |
| SimpleGraph-SMW | SMW |  | https://en.wikipedia.org/wiki/SMW | makes Semantic MediaWiki accessible via the SMW API |
| SimpleGraph-SNMP | SNMP |  | https://en.wikipedia.org/wiki/Simple Network Management Protocol | makes Simple Network Monitoring Protocol accessible via SNMP4J |
| SimpleGraph-SQL | SQL |  | https://en.wikipedia.org/wiki/SQL | makes relational SQL databases accessible via the Java JDBC API. |
| SimpleGraph-TripleStore | TripleStore |  | https://en.wikipedia.org/wiki/Triplestore | makes BITPlan's SiDIF educational TripleStore accessible |
| SimpleGraph-WikiData | WikiData |  | https://en.wikipedia.org/wiki/Wikidata | makes WikiData data available via the Wikidata-Toolki API |
| SimpleGraph-Word | Word |  | https://en.wikipedia.org/wiki/Word | makes Microsoft Word Documents accessible via the Apache POI API |
| SimpleGraph-XML | XML |  | https://en.wikipedia.org/wiki/XML | makes XML dom parse results accessible to Graph processing. |

Motivation
Solving IT Problems across System boundaries can get very difficult. There may be a wealth of APIs which first looks helpful but given the diversity of approaches it a daunting task will need to be tackled to get reasonable results. More often than not projects are not even started since the cost/benefit ratio is not good enough. SimpleGraph aims to supply a unified graph API access to Systems for which this makes sense. In fact for most systems it makes sense to have a graph API. Quite a few problems will get much easier to solve if the subdivision of the problem is done with the goal to apply graph algorithms.
Use Cases
Mix and Match Office and other data
Let's assume we have a business that works in the following manner:
- There are pricelist for product categories in Microsoft Excel files
- Product specifications are in PDF Format - the files are referenced in the Excel files
- Invoices are written in Microsoft Word
- There is an address book of customers in VCard format
- Orders are handled via e-mail (that is automatically produced by the companies shop website)
- Monthly reports are created with PowerPoint
The monthly reports should in the future be modified to give geographical information. Basically a revenue/region sales count per product/region information is wanted.
The 1000 dollar question - can this report be created efficiently semi-manually with reasonable software effort? Sadly it sounds more like 10.000 or 100.000 dollar question.
There are at least 6 different systems involved. SimpleGraph simplifies accessing all 6 systems.
