typealias AttributeDict Dict{UTF8String, Any} is restrictive?

[CorySimon]

Can we change:

typealias AttributeDict Dict{UTF8String, Any}

to

typealias AttributeDict Dict{Any, Any}

?

I don't see the point in restricting the keys of the dictionary that is an edge attribute to UTF8String. In fact, why not just construct ExEdge with a Dict()? It seems to unnecessarily complicate things to introduce this AttributeDict type.

UPDATE:
For example, I want to store a tuple attribute to each edge. So I need to do:

attr = AttributeDict()
attr["uc_direction"] = (0, 1, 0)
edge = ExEdge(1, 3, 2, attr)

Oddly, this code:

edge = ExEdge(1, 3, 2, Dict(utf8("uc_direction") => (0, 1, 0)))

throws an error:

ERROR: MethodError: `convert` has no method matching convert(::Type{Graphs.ExEdge{V}}, ::Int64, ::Int64, ::Int64, ::Dict{UTF8String,Tuple{Int64,Int64,Int64}})
This may have arisen from a call to the constructor Graphs.ExEdge{V}(...),
since type constructors fall back to convert methods.
Closest candidates are:
  Graphs.ExEdge{V}(::Int64, ::V, ::V, ::Dict{UTF8String,Any})
  Graphs.ExEdge{V}(::Int64, ::V, ::V)
  call{T}(::Type{T}, ::Any)
  ...
 in call at essentials.jl:57

@CorySimon, as you can see, Graphs.jl hasn't been getting much attention recently.

Are you still interested in this issue? If so, are you able to submit a pull request which addresses this problem? If you're stuck and looking for hints, I might be able to provide some.

@kmsquire, this package is not maintained anymore? What is the defacto standard package for graphs in Julia?

[mlubin]

LightGraphs.jl is actively maintained

[juliohm]

Thank you @mlubin, I assume it took the place of Graphs.jl?

[mlubin]

The functionality of Graphs is not entirely contained in LightGraphs (and likely the reverse statement is true as well), so I'll let you decide which you prefer.

I see that lightgraphs has maximum flow algorithms, all I need for now. :)
