1.3

Compatible with Gephi 0.9.3 and above. Note that part of the specifications were already implemented since 0.9 but full support is only guaranteed in 0.9.3.

• Add kind attribute on edge to support multi-graph (i.e. parallel edges)
• The edge weight is now a double instead of a float
• The edge id is now optional
• Add xsd:longas possible idtype on <graph>
• Add new attribute types bigdecimal, biginteger, char, short and byte
• Add new list attributes like listboolean or listinteger for each atomic type

Dynamics

• Add a timezone attribute on <graph> to use as a timezone in case it's omitted in the element timestamps
• Open intervals attributes startopen and endopen are removed. Use regular inclusive start and end instead
• Remove start and end attributes on <attributes> as it was redundant with <graph> attributes

Timestamp support

Add the ability to represent time with single timestamps instead of intervals. We want feature parity between the two time representations but note they can't be mixed.

• Add a timerepresentation enum in <graph> with either interval (default) or timestamp to configure the way the time is represented
• Add timestamp attribute to <node>, <edge>, <spell> and <attvalue> to support this new time representation

Alternative to spell elements

• Add a timestamps attribute to <node> and <edge> to represent a list of timestamps without having to use spells
• Similarly, add a intervals attribute to <node> and <edge>

New slice mode

The optional mode attribute on <graph> now has an additional slice value, in addition of static and dynamic. With slice, the expectation is that the <graph> also has either a timestamp or start / end intervals.

• Add a timestamp attribute on <graph> to characterise the slice this graph represent
• Change the meaning of the start and end attributes on <graph> to either characterise the slide instead of the time bounds, which should rather be inferred

Viz

• Add hex attribute on <color> so it can support values like #FF00FF
• The z position is no longer required
• Dynamic attributes like start, end or child elements <spells> are no longer supported for viz attributes. To represent viz attributes over time, an alternative is to create multiple graphs each representing a slice

1.2

Compatible with Gephi 0.8 and above.

• The node label attribute is now optional
• <meta> should be placed before <graph>

Dynamics

• Rename the timetype attribute to timeformat. This attribute is set on <graph> to specify how time information is encoded, either like a date or like a double.
• The timeformat is currently either float or date and default value is date. The float type is replaced by double, and is now the default value.
• Added timeformat types integer and dateTime. DateTime is equivalent to timestamps.
• Add open intervals (non-inclusive): startopen and endopen attributes.
• <slices> and <slice> are renamed <spells> and <spell> respectively because slices are a different concept as remarked.

Viz

• Add viz attributes support for dynamics.
• Add the alpha channel to RGB. Colors are now encoded in RGBA. It is a float from 0.0 (invisible) to 1.0 (fully visible). If omitted, the default alpha-value is 1.0 (no transparency).

1.1

Compatible with Gephi 0.7 and above.

• Modules are stabilized and new ones appear: hierarchy and phylogeny.

1.0

Compatible with Gephi 0.6 and above.

First specification. Basic topology, associated data and dynamics attempt constitute the core, plus a visualization extension.
